The Accurascale Class 37 is a fantastic model of the English Electric Type 3. Unfortunately one of the six that I purchased has a problem. In this video we troubleshoot an Intermittent Power Loss problem with D6702 and we show you how to fix the leaking oil issue. This is part 1 of a three part series. Part 2 walks you through a complete tear down of the Class 37 and can be found at • Accurascale Class 37 -... from 6pm GMT on January 5th 2024. Part 3 will follow in a few weeks once we have the parts on hand necessary to fix the loco.

Thanks to everyone who took the time to comment. The problem turned out to be an issue with the motor. Accurascale got a new motor dispatched to me within 9 days to the USA, so hats off to them for excellent customer service. You can see the motor issue in this video here -> th-cam.com/video/8b_DDQiNW5k/w-d-xo.html.
My class 37 has been returned to accurascale for repair with exactly the same problem as yours but I'm dcc sound! It came back, a different loco, that had obviously been returned by someone else, and that was worse. Its on its way back. One thing I did check was ghe power being drawn by that 1 loco and it spiked up to 1.7 amps. I sent accurascale the video to which they said it seems a bit high! Cheers Andy
Love the class 37🎉 thanks for sharing
Charlie @ Chadwick Model Railways has documented this and posted a TH-cam video.
Charlie indeed had very similar problems, particularly the puddle of oil, but the biggest difference is that he runs on DCC, and other problems he had were down to the decoder.
@@delboy1727 Not exactly. Charlie shows three locos in the video.
With Charlie's one (green with split headcode boxes), he never diagnosed the issue, he bounced it straight back to Accurascale under the Warranty. I suspect it had the same issue as this one. He was sent the derailing one as replacement.
The other one in the video, the Direct Rail Services one, is one owned by someone he knows that's already been replaced under warranty. It's the one that has the failed decoder and that Hattons is denying to refund.
@@jdenm8 Because it had been modified by the owner .
Think he only added the crew and weathering to his model but reading Hattons T&C's still a violation of their T&C's@@shauntaylor9251
Why is it when railway modellers have a problem with a new locomotive they insist on taking it to pieces. The first problem is that it probably invalidates the warranty and they may not cure the problem. One assumes that if they buy a new car or washing machine they don’t start taking it to pieces if they have a fault with it. My feeling is that manufacturers play on this principle it doesn’t matter if it works or not the buyer will just fix it. Has not the time come to return faulty goods to the shop and exchange it, there can be nothing more disappointing to a young new modeller to the hobby to maybe have waited a long time for their locomotive to take it out of the box and it doesn’t work. The more of us that return faulty products the better they will become going forward. Remember it costs manufacturers more to keep replacing product than getting it right in the first place.
The return policy mate. Railway modellers wait a very long time to get these new locomotives, they sell out very quickly and the manufacturers only retain a limited stock for warranty replacements. Good chance if you return it, you'll end up with no loco and your money back, or waiting a very long time for a repair (based on some of the comments people made here).
@@Oorail what you are saying then is that as consumers we are expected to accept any rubbish that manufacturers want to churn out. That attitude will only result in even worse product not better.
@@johnswain1092 Not at all mate, you should never accept rubbish. I'm saying the outcome I want is that I have a working D6702 as soon as possible. If I were to return it, that is very unlikely to happen. The best option for that particular outcome is to repair it myself. By taking it apart and finding the root cause of the problem, that makes it a lot harder for any manufacturer to ignore. Just looking over the comments since yesterday, looks like a lot of people have the same issue and across multiple models, so looks like Accurascale has a motor problem that they need to address in their supply chain. Seeing the way they typically handle things, I would be surprised if we see the same issues in future models.
It’s not just the model railway industry. The games software industry for years has worked on a “release it broken, fix it later” strategy. If consumers voted with their wallets instead of fawning over pretty details and pretty graphics then maybe things would change. Until manufacturers are taken to task things won’t change. It’s why most sensible modellers have woken up to the fact that Hornby can’t cut the mustard anymore. Ya can’t keep getting burned over and over again.
Seems they have a problem, Chadwick Model Railways has just released a video about his as well.
It's a mess send it back I feel your pain and disappoiment been there done that well done for trying to sort it 👍
spooky,just been running my class 37 accurascale dcc .not running ,speed erratic.so have a break went to youtube and saw your video.no oil, have not checked dipswitches .will do this and clean wheels .if fails back to accurascale,My bachmann class 47 works great on same track
That is definitely a bit spooky.. Mine is definitely the motor. Seems to be a common problem looking at the comments on my last two videos, looks like there are contaminants around the commutator which are causing problems. I've got two other Accurascale Class 37s that I've only briefly run, so I'm going to have to test them out more aggressively this week and make sure they are ok. Seems to crop up after they've run for awhile. In my case, I ran it in both directions light engine for about 45 minutes each way, then another 30 minutes under light load before it started to give problems.
Great video - I have the same problem with my Acc 37. I was interested to see you do the dip switches - but that part wasn’t in focus… all the best, Julian
Thanks. There definitely seems to be an issue with the Accurascale 37s. Sorry about the focus issue on the dip switches, I did notice it after uploading, its an issue with the GoPro. I have another video coming out related to the dip switches which I filmed with another camera, so keep an eye out for that over the next day or two.
Sorry - wasn’t meaning to get at you..but much appreciated! I’m impressed you have tackled these issues head on - having fantastic detail etc etc is great but if they don’t run great it’s a major disappointment to all of us. Come on Accurascale - quality control!
One of my 2 Accurascale Deltics have had this reoccurring problem since new . I should have sent it back .
I agree a good clean is in order even removing the base keeper plates to remove oil.
However I think it could be the motor. Realised you’re running DC, otherwise I’d say backEMF on decoder.
The oily base keep plate is a red herring as to the poor running fault with all Accurascale locos, it's the motor. Specifically dirt in the commutator grooves causing a partial short circuit across the inductive windings. See my other communications written on this video's comments for more details and how to fix it. Regards Julian
Accurascale need to up their game otherwise people will stick to Bachmann
Bachmann seem to get a lot of stick over their pricing, but the last time I had to fix a brand new Bachmann locomotive was 9 years ago and that was to correct a design flaw with their Derby Lightweight. I've definitely bought a lot more Bachmann locos than Accurascale ones.
@@Oorailyou’re lucky. i’ve had two bad Bach 47’s in the last year alone. Squealing motors.
My accurascale manor class was returned as it ran badly, in my unboxing video it seemed ok until later I noticed it "bobbed" as it ran. Returned 5th September and I'm still waiting for it to come back. Very disappointed.
Strip off the base plate take out the wheels gives you better access to clean the wheels and the pick ups
Thanks that was a real pain between being careful not to break the chains and the tiny rods on either end.
Every Accurascale loco I've bought has done this speed variation, two 92s and three 37s.
It always occurs after a few weeks running.
I have heard that the problem is the brushes being copper and using carbon brushes cures the problem?
The two 92s I returned for refund and one 37, the other two 37s? I really wanted to keep them.
Fortunately I found someone who knew the solution to the problem and they replaced replaced the motor in the remaining two 37s, they now run perfectly.
I use DC analogue.
Hope this info is helpful.
This looks very much like the problem I had with my Accurascale class 37. Mine was 37419 DCC ready version. The motor was the fault with the slow running but I had other problems as well, after the 3rd return I had a full refund. Purchased a Bachmann class 37 as replacement and have had no problems at all.
Sent mine back in October ,,,,still hav`nt heard anything ....poor running etc ,,,i`ve got 20 yr old Lima loco`s which run better....
It takes a long time for Accurascale to fix on average 6 weeks. This means I have lost 18 weeks with my locomotive. That's why I had a refund . I am worried about a preorder class 31 might have the same fault.
Picked up a good Intercity Bachmann Class 37 (before A/Scale) detailed model, looks good and on my limited parallel track (not got space yet for a layout) runs quite well, was a good sale bargain from Hattons about a year ago Feel sorry for the hard workers at Hatton from the dreadful news yesterday that Hatton soon will closed.
You get what you pay for . Never have these issues with the new Bachman 37 .
Me neither, including my bachmann class 47, all my 44`s, all my 45`s, all my 25`s.
Why didn't you take the base keeper plate off each bogie and deal with the root cause instead of continually cleaning the symptom?
For this video I was trying to avoid taking it apart, as you can see by my follow on video I didn't avoid doing that. The source of the oil isn't actually from inside the bogie, its from the worm gear at the top of the bogie being over lubricated. The gear sits in an open frame, so as soon as it starts moving it starts throwing lubricant out the top of the frame and it leaks down the side of the bogies. It wasn't doing it on the bench because it was upside down, but as soon as I ran it on the layout again it would start to leak down the bottom. Whats interesting is that the other bogie didn't have this problem, it had less lubricant around the gear and it wasn't as thin.
I could be wrong but Lakeside model railway had the same issue with one off his deltics, accurscale fixed it (I think it was motor related)
In my case in my Deltic, the motor would sound like it was working , but no torque whatsoever. Accurascale sent me a new motor and I replaced it myself. Like you, I’m state side. Deltic has been fine since.
Thanks for making this comment. Sounds like I won't have any issues with Accurascale sending me a replacement motor :)
A/scale should ideally few this issues in house / China house and ship them back, if there's a batch of affected loco's do a recall@@Oorail
When you say "rubbing alcohol" is that IPA? And where can you buy it from? Thanks.
Yes its IPA, I'm using 91% IPA. I'm in the USA, so I typically buy it at Walmart. In the UK, you should be able to buy it from Boots or any chemist, or on-line at Amazon UK. In the UK its called surgical spirit.
Is your power integral? Do you have droppers to each and every piece of track? High resistance on any of your rail joints, especially intermittently, plus humidity and temperature variations, will definitely affect running.
Just return it to Accurascale for replacement, if so.
Its not a power issue with the layout and it looks like you missed the part of the video where the other Accurascale Class 37 goes around the layout just fine. The motor on this 37 is running at about 20-25% of the RPM that it should be due to an issue with the motor. Returning it to Accurascale would take quite awhile, so I went ahead and just fixed it myself. You can see the running issue with the motor on this video th-cam.com/video/8b_DDQiNW5k/w-d-xo.html
It's the commutator in the motor that needs cleaning out. The gaps between the brass contacts get clogged and short circuits part of the inductive loops resulting in slow running and higher current requirement. Check out Peter's YT channel Torridon Road from a couple of months ago when his 37 motor failed, he did two back to back videos on it and how to repair it. It requires removal of the motor and opening it up. Regards Julian
On a new loco?
Thanks. I was able to get the motor out as you can see from my other video. I just watched his video this evening and it looks like the non-serviceable motors can be opened. So I'm definitely going to give that a try over the weekend. I guess I should have tried opening these motors before, just didn't bother because other manufacturers said there were no serviceable parts inside.
Probably a manufacturing defect like solder or wire making contact where they shouldn't. They only QC the motors for less than a minute, this problem only showed up on mine after over an hour of running. Peter's video is useful since it shows the motors can be opened.
@@fatwalletboy2 You better believe it! I am speaking from personal experience. The problem usually starts to show after an hour or more's use. I think either there is dirty, oily deposits from the factory manufacturing process inside the motor or perhaps the carbon brushes are too soft and wearing into the commutator gaps. Bachmann had similar issues about 12 years ago on some of their 37s and also 66s.
@@Oorail Yes, they usually start to display problems after an hour's use, although I have some lasting 6 or seven hours and then failing. Unfortunately it is the Achilles Heal of Accurascale locos. Many people keep their locos new and boxed up, or just use them rarely so they don't realise the inherent problem!
decoder sound set to high. amplifier sucking power. turn down to 150
Thanks but this is the DC version.. so at least I don't have that problem. That problem seems to be a default issue with the decoder though. The 255 value they ask you to lower to 150 is the maximum you can store in an 8-bit number. I think 255 is probably the default value on the ESU decoders, so depends on whether ESU was supposed to supply ones customized for the 37 or if the Accurascale factory missed a batch to reprogram. Only Accurascale can answer that one..
I must be missing something here. You bought six (that’s a significant expense) at least one of them does not work properly. Dip switches set incorrectly, oil leaking, dirty motor. Why on earth is it your responsibility to fix the problem? Sure if a product as supplied has a fault, it should be returned to the retailer/manufacturer?
Interesting though it is to watch your work, reading comments and watching other videos, ‘problems’ with the Accurascale class 37s are pretty common. I definitely won’t be buying one.
There are so many videos up now! Faulty motors, decoders ect! 😢
There is definitely an issue with the motors. It looks to be caused by debris, dirt and other contaminants inside the motor itself. Seems to be an easy enough fix once you get to the motor, but I am letting it run for awhile to make sure its definitely fixed. The sound decoder issue looks like the Accurascale models need specific settings and the ESU decoder maybe set to defaults. I'm not sure how they program decoders at the factory, if its done by the supplier (eg. ESU) or if their factory programs them. I've got six Class 37s, and none of them had the correct dip switch settings for the DCC ready models that I have. The decoder issue sounds like you need to check the volume is at 150 and not 255 (max). However its still possible to set the CV to max, so Accurascale may need to revisit the electronics a bit to make sure its not an issue in the future. The motor issue, at least in my case and seems like in a few other videos, doesn't show up immediately. If you have one of these models, I would run it in both directions for about 45 - 90 minutes each way, and make sure you don't encounter any problems.
After the Chadwick video and now this I cancelled my order. I don't fancy either the aggravation or disappointment.
At £169.99 each ......what a load of crap .....Buy Bachmann no issues ,why should we have to start pulling things apart ,,,,
agree.
Why are people trying to fix a brand new model... that should be for accurascale to sort out... not let other people find fixes for their crap.... I would have had several of their models but glad i havent cos i haven't the time for all this s#@t... if people keep on fixing their problems the more they are just going to keep churning out crap... The new hornby!
I’ve many accurascale models and all work brilliantly. It’s a shame when people have issues but that’s true of every manufacturer. I’ve had two rubbish Bachmann 47’s in a row.
At last. Someone who can see this current madness for what it is. Meanwhile another manufacturer is boasting about how many parts make up the bogies on its new model while overlooking the fact that the cab is the wrong shape entirely. We seem to be obsessing over the details and ignoring the basics. My wallet stays closed.
Kitbashing and nursing stuff to run is one thing if it some old Hornby or Airfix thing you picked up at a fare. Very different for a £300+ ready to run model.
The only problem that bugged me was the camera constantly being out of focus!!!!! Filming with a potato per chance? Was hurting my eyes... had to stop watching. 👀 😂
Thanks for the feedback Gary. I've spent the past couple of weeks making some modifications to the GoPro-tato and you should see a marked improvement in upcoming videos! If you don't, you might need to visit your local Specsavers! :)
Another expensive fail. Just as I pointed out in my video about the Hatton’s Closure
They are very nice models, think they are just let down by some faulty parts in their supply chain. Difficult problem to solve as the increased QC to catch those issues would drive the price up considerably. As for Hattons, I get the impression their ownership made a business decision to exit the market. They recently bought MB Klein here in the States and moved it's operation to Nebraska, I've been told it will remain in business as an online retailer (modeltrainstuff.com).
send my loco back to retailer, rails of sheffield.IF NO REPLACEMENT, THEN REFUND AND TRY AND BUY BACHMANN NEW 37.I HAVE A CLASS 47 WHICH IS GREAT.FUNCTION F2 WHICH BREAKS THE LOCO.THIS IS ON THEIR NEW CLASS 37 .Maybe there's a large batch of poor motors made in china.that serve Accurascale.
Give it back to accurasale..it it not your task to repair a brandnew loco !
