Model Train Maintenance: Mainline Locomotives

hello everybody and welcome back to the railway once again today it’s a slightly different video I’m not doing any money because a lot of the videos that are meats and of showing the servicing and upkeep and maintenance all of those sort videos are being surprisingly popular so I thought I’d do another video showing the service of another different type of locomotive specifically the mainline locomotives now these are quite old I believe they were replaced by Backman or at least the company mainline was purchased by baikman and now operators Backman but there’s still a lot of these mainline locomotives about on eBay especially the four six those which look like this they’re all different there are all different locomotives but they all have essentially the same chassis and it’s quite straightforward to service them it is a bit fiddly but it really isn’t too bad it’s really not too bad so it’s just gonna be a quick video just showing how to service them how to get them running nicely because they do they don’t run very well if you don’t service them so yeah I thought that’s what I do so I’ll show you what we going to need first you’ve got to need something to cradle it in now you can buy us something specifically to hold the locomotive I don’t know who do I think it’s from the gauge mast or something like that I’m not your target sure but I just use a piece of foam it live looks like some insulation or something I’ve used them for many years and they’re very very useful and very very good of course you’re going to need your small selection of screwdrivers as always just to get get in I normally just have these two you want six volts or access to six holes leave that’s working possibly not now I know the locomotives are 12 volts but when we’re just spinning the wheels gently we don’t really want them flying round at full speed so six volts you know between four you know for another 107 you don’t want too much just to get the wheels turning so that you can clean them you’re also going to need a paintbrush I suppose that’s optional of course scenery on it yeah that’s optional but you could use a doorstep instead and that’s just to clean the body that’s just a cosmetic thing you shouldn’t need a file for this one this one’s very straightforward if you’ve got a file then if you found somewhere to use it that’s fine oil just light machine oil the sewing machine oil from Amazon is very good that’s what’s in here although this is that gauge master oiling pen which I’ve had to hot glue the top on because it’s it leaks so horribly I don’t recommend those really and then you want some cleaning agent this is not green food colouring as always this is just household nail polish remover or you can even use anything you like as long as you steer clear of wd-40 which I think I’ve explained why’d you lose that and of course some tweezers again it’s optional but if you spot a hair or something caught up in the wheels or the linkage or whatever these are very useful just to snip it out no rip it out because obviously you don’t want hairs you want this logo to run as well as possible anyway let’s get on enough rambling on I’m gonna put the tender to one side I’ll try not to forget about it because I often do but there’s not much to do with the tender really just a wheel please now the first thing I always like to do with any locomotive whether it’s mainline or not is just give it a little brush now you wanna be careful especially if it’s a super detailed model you want to make sure that you’re not going to rip off any of the detail parts I suppose mainly hand rails vacuum pipes you know that sort of thing but this is just brilliant for well there’s a a siren in the background sorry about that yeah this is brilliant for just removing any dust or debris especially if you don’t keep the logo in its box it just gets rid of the dust and that’s why it’s optional if you keep it in a box it really isn’t going to be an issue once you’ve done that that’s when this whatever you’re going to use to hold the logo upside down comes into play so the next thing I always do is give the wheels are clean now a quick note when you’re putting anywhere go into this sort of cradle you want to make sure you’re not ripping off the smoke deflectors or handrails when you putting it in so I like to spread it out first and then lower the logo in very generally our mainline wheels don’t really get very dirty there’s a few little blobs of dirt but generally they’re very very clean locos let me try and get this in the shop perfectly that’s a bit better and it’s basically the same drill now if your logo if you know if you’ve only just got the logo and it’s not running

you could probably save this step till a little bit later but you are going to want your local running now I don’t really like turning the wheels I’m screaming at the same time because it’s very hard to avoid scratching the logo but that’s you know that’s up to you anyway cotton buds I forgot to mention that in the ingredients you just need some cotton buds or any suitable ringing agent or cleaning I don’t know utensil let’s say and all of them is just dipped the cotton bud into the cleaning fluid a little bit soaked into it and start to clean so you hold the opposite we obviously know I think that’s a permanent mark on there now if it’s really tough stains it’s going to be difficult to get them off but I wouldn’t worry too much because as long as you making contact it’s absolutely fine so you clean all the surfaces that are visible and of course you need to clean the bokya truck wheels if you’ve got them and then this is where the power supply comes in so I think to remember where the wheels are so depending on how much of the wheels you can access we’re at about I don’t know eleven o’clock there so if I take it to five o’clock round here that’s how we can clean the other side no you could do it in quarters but because I can get the most of these wheels it’s fine to do it like this so about there so that’s turn the wheels and this way we scrub very whereas if you just applied power here and this you know you’re gonna get cropper our plates are going to damage the wheels which is not ideal of course it just give them all clean on the other side I realize you can’t see exactly what I’m doing but I think you’ll get the gist let’s try and it was cleaned and of course that’s not bad sometimes they’re a lot dirtier than that but that’s not bad now with these wheels you’re going to want to take these bogie wheels off because that’s how we get the body off so we’ll take those off and I probably prefer cleaning these when they are off actually so we’ll do that and it’s just the exactly the same but it’s perhaps a little easier I’ll just grip them like this being careful not to dégagé them I don’t think you can with these they’re fixed in place but some of them do slip off the axles if especially the old of trying ones or some Holmby ones so just be careful these aren’t really that bad but I would clean them anyway to screw it’s good practice and then you don’t forget all right that’s clean now before I do take the body off I like to boil the axles it doesn’t really matter what all you do this in no I would suggest oiling the linkage last sorry I know you couldn’t see that I would recommend oil in the linkage last because when you’ve got to handle the body and the chassis you don’t really want to be taking all that oil off with your hands so yes that’s that’s what I prefer to do doesn’t matter if you do it a different way at all but yes so oiling the axles let’s see if I remember how to do this so you’re gonna want to pull the the truck to one side because there’s a screw just underneath it you just have to get that off anywhere you can it’s not that you just think in the world to take the truck off so I like to leave it on and that’s probably come out so I’ll let that come out when we take the body off but you want to take up well this particular model has four screws and assuming it’s the same chassis on all the other four sixes which I think it is it should be the same all the ones I’ve built like this and four six o is very common from the mainline the collet is a little bit different and the class m2 is very different because it’s got a different motor altogether it’s closer to a try and locomotive the mainline / Airfix n2 but anyway let’s see that body is now loose so we’ll leave the body somewhere else from this local actually because it’s such a big Chasse can stand up on its back end quite nicely so what we should do now is just take it by the back and lift lift the base off and you’re going to want to clean this if it’s covered in oil but this one isn’t which is good and then what you’ve got is full access to the axles now at this point if you see any hairs around the axles or anything like that you should try and get those out though I don’t recommend taking the wheelset out because then you’d have to take off all

the linkage and for a routing service it’s not worth doing all that right oil in bed this is where that comes in and you just want to give a generous but careful amount to each axle now the mainline axles have been known to fail so if you keep an eye on those that’s also good now you want a little blob on the gear it should be the rear wheel that has the gear let’s see for this let me just focus this make sure it stays focused in this case it’s the rear wheel as you can see I just put a little blob of oil on there not too much and if you’re happy that that’s all nicely lubricated you can then pop this back on and screw these two screws back on though you’re going to want to leave these two – at the end so you don’t want to leave that one that one you will leave those arms because they’re to screw the body on so you want to lower this thing back on I mean you could probably get it on by hook or by crook but they’re quite tight-fitting you just need to apply a little bit of pressure just to get them on there and of course all the screws should line up let’s zoom out again I try to think of the best way to let you get the best of you now all the screws look the same so always be careful of that if you’re taking screws out and you start to notice that they’re all different lengths you can you can get in a mess so I just you know try and remember the most homely ones at least I think most mainline to do all we use the same screws cause you know or if they are different they’re obviously different not very slightly different so that’s all we need to do for the wheels firm at this stage so then I like to move on to the motor again you can do this in whatever order it’s not about to be this is the order I like to do it in now I tend to light on its side the chassis for this part though just be careful because of course you’ve got lots of delicate gear and stuff on the side and basically what you’re working on is this here I’m gonna turn the exposure up slightly for this bit because it’s quite delicate work now this is what you’ve got to be careful of because you’re gonna be undoing these two screws and when you do so the spring and possibly the brush are going to fly out toward you so as you’re unscrewing the might hold them in place and get the screw out so let’s do that my way now it’s not too disastrous if you lose one of the springs and I believe you could try the Hornby ones from the whip ring field motors and those smart fit as well but it’s best if you don’t anyway now this little brush well let’s say I don’t know this little piece of metal it comes out you need to just gently lift it out and there’s the spring just there that’s the spring that’s just fallen out and you want to rescue that and put that somewhere very safe because if you lose that that isn’t especially good and of course the little little plate or bracket you need to look after as well now it’s very important you remember which screw you took out from here and here because they’re different one of them has to reach through to the back side of the chassis to take the you know take the electricity from that side and the other one is is shorter so remember which ones which I’ve tend to leave them in there in the bracket so that I know but that one was the left one and that looks like it’s the longer one but we’ll see when the other one comes out right so the same drill with the other one I’ll turn this around scuse me one just do that and it’s the same thing you’ve got to make sure that brush that spring sorry doesn’t escape you because I’ve had to fair it around on the floor many times looking for those flaming things yes that was the shorter one so as you can see only put it in that’s considerably shorter and that one was on the right and rescue the spring now the brushes often stay in there but you can get those out afterwards so now you should be ready to remove this this little plastic plate so let’s get that off like that oh and the whole armatures come out now normally that wouldn’t happen so I’ll show you what you’d normally get there’s the brushes these are the brushes you want to look after these as well because they are a bit difficult to replace if you lose those right there with music alright so this is what it will look like when you get it out the armature will be in here now before you take it out it’s worth noticing this

little white washer type thing let’s see we can get a close-up of that now these are loose these little white rings and you want to be careful that you don’t lose those I don’t take them off but if they do come off that’s where they go there’s one on the back as well well I think there’s two on this one yeah on the back so just be careful that you don’t lose that now I do take this well there’s the commutator but I do take the armature out but again be careful with it because if you ripped or anything no wires on it well the local won’t enjoy it now when you take the arms you’re out you’ll see that there’s a gear exposed in there on all I do is put a little blob of oil on it like this hope you can see it just a little bit you can turn it round as well just make sure it’s well oiled and a little bit of oil you know on the whole wall above it which means that the armature will turn nice and freely next the armature itself it’s just a case of getting the cotton but again let’s get another one of those another cotton bud and a little bit of nail polish remover in my case and you want to clean this off now this one isn’t dirty at all but it often is deceptively dirty as you can see is reasonably dirty now you just want to shine those up so they look nice as you can see my little white rings come off already so you want to be careful of that and the brushes you want to keep to one side you don’t want to put the brushes back in at this stage when you put the armature back in though you can put a little bit of grease on the gear that’s on the armature again not too much with the grease and making sure the little white washers are still on there you just pop it back into its hole and make sure it’s seated into the axle folder or whatever it is and that looks nice now there’s no point trying to balance the brushes on there and then put the plastic casing back on it’s just not going to work but the brushes do fit through these holes so you can stay like that as I’ll demonstrate providing it’s the right way it will click back in there we go that’s the most part of the service till now it’s just reassemble put all the wheels and things back on grease the linkage and give her a try right let’s look now you pop the brushes back in now I used to clean the brushes but there’s actually very little point in doing that because they’re sort of almost self-cleaning there’s a lot of friction going on if you want to clean them by all means do but because they’re so they’re quite hard to come by I don’t like leaving them because it wears them out even more unnecessarily trying to get these back in it’s a bit awkward getting the brushes back in the holes but it’s not too bad you can normally do it in the end if you really want to you can just use some tweezers which I might have to do with this one because I’m going to be here trying for a long time so let me see what I’ve done with them they go in in the end it’s always a bit awkward actually getting those in but it always works in the end now don’t put both the springs in at the same time I’ll put one in first and then deal with that and then deal with the other one so just one first it just goes in over the brush doesn’t matter which way obviously same with the brush the brushes go in whichever way well I suppose clean side up alright so remember the screw that is the longest goes on the left and with the spring standing upright like this you just pop the spring over the top of it I know you can’t see this too well and push it down holding it in place like that while you screw it in again if you accidentally release this the spring could ping away and it’s a long hunt assuming you ever find it at all I’ve lost a couple in my time screw that back in slowly you don’t want this to be loose try that again there we go nice and tightly not so tightly but you’ll never get it off again but nice and tightly right the second spring goes back in again I don’t know how easy it is to replace these Springs if you lose them I’ll never never never had to try luckily yep so the shorter screw goes in next hopefully I’ll see this a bit better so the Springs upright again pop up on top of the spring and then screw that in I know you can’t really see but you can tell what I’m doing and it’s just essential that the spring is nice and

straight and that should work now if it doesn’t work straight away don’t worry because if it just depends on the position of the commutator you can test it by taking your voltage again just like this and just applying very quickly to the two sides now this doesn’t always work straight away so I’m gonna put the full 12 volts in because you’ll need to then run it on the tracks for a while but as long as you get something like that you know that you’ve at least put you know put the brushes in the right way and sorry you put the screws in the right side and you’re not you’re not going to get any running issues with it and it’s not shorting or anything like that so that’s good so we know it’s working we know that the brushes are in place correctly in the springs and making contact with them and whatnot at this point I would recommend putting the body back on before you start really touching the wheels and oiling the linkage because you don’t really won’t be touching it after you’ve all over linked it you want to let it run for a little while so this low is back in now it’s worth pointing out if the inside of the body is a little bit greasy let’s see like that I just take a dry off the hood I’ll just give it a clean now because the less unnecessary grease you’ve got the loose in there the better just make sure it’s clean on the inside it’s more an issue with trying locos really because those motors do throw a lot of grease out but with mainline – it’s worth just making sure the inside of the body is clean and then you just place the chassis back into the body now there’s no hooking mechanisms or anything you just drop it back in because there’s two screws it can just drop in and you screw it back in now if you remember I left this screw in place so I’ll just screw that one bucking now not all the way because you’re not in yet the other screw goes in at the back as you remember this is a magnetic screwdriver so it’s a bit easier it’s very difficult to get the back screw in sometimes so a magnetic screwdriver is possibly the way to go that’s it yep that’s secure right now because the bogie wheels are perfectly insulated and it’s a plastic bogie slush truck you don’t have to pay attention to which way the wheels go so you just slip them in and if you didn’t see how I took these out earlier by the way it’s just the case of pulling them out they’re all quite easy to get out let me move this so you can see it so you just place it in like that in place and then just click it in and that goes in right nearly ready just take the oil in pan and put a little blob on every moving part so big one bigger one they’re tiny ones on each side and little bits on these moving parts I like to put a bit around the valve as well I’ll then flip around and do the other side too very easy it’s quite easy to get these locals running well but having said that it’s very very easy to to get them running poorly as well and if they haven’t been service for six months or so you’ll notice that I reckon because I I often notice just how badly they run if you’re not if you’re not servicing them regularly right ten the time I’m just gonna give it a little brush with the brush make sure all that lists away now this is kept in my little tender cabinets so it’s not really that bad and the wheels are clean as well but if they’re dirty again you just get your cotton wool and clean them like that make sure the tent is well cleaned and we’ll see if the locomotive works now it’s all back together okay so the loco and the tender are both on mine and what you basically want to do is give them about 10 to 15 minutes of running very very slowly to start with as slow as you dare because remember there’s a lot of oil that’s you’ve placed on the gears and whatnot so you want to make sure that that’s all worn in before you turn off the speed otherwise it will go flying everywhere but essentially they won’t run there won’t be much of a difference to start with but you know Ashley’s run for five minutes all your lubricants gonna start working into them into all the different parts and hopefully you’ll start to see some improvements so I’m hoping she’s gonna work full stop but she just had to do one lap slowly and then speed up to about six volts or six o’clock and sorry all 12 o’clock and we’ll see how we go

from there so let’s see four forwards yeah so a bit jerky but you get it happy there we go that’s nice and slow and that’s actually very smooth that’s not bad at all right I’ll be back with this in a minute then going a little bit quicker and we’ll see how she’s we’ll see how she’s running okay back in a minute right so she’s chugging along very happily now as you can see no complaints they’re doing very nicely so I hope that video is helpful to you if you’ve got a mainline loco but you inter-service I’m sorry we’re not really able to see too well what I’ve been doing but I hope you’ve managed to get the general idea I’ve been doing a lot to service in this week so that’s why there’s not been many videos out so hopefully there’s going to be a little bit more running in the weeks to come so stay tuned for that and I’ll see you all very soon thank you all for watching and I’ll catch you soon thanks guys
