Klasse 37 - Colas - 37421 - DCC lydmonteret

Another excellent 37 from Accurascale. Runs really well. Sound is just like the real locos. Livery is very striking and well applied. Etched grilles really stand out.

Only very slight negative is that it was missing one of the kickplates on arrival.

Excellent model, nice touch with the working fan.

Top marks again.

Superb model, a well deserved 5/5.

The model is packed with detail, from the very fine etch grills and handrails to lamp irons all perfectly within scale.

The detail is just limited to the outside, the wonderfully detailed cab interior is clearly visible through the crystal clear windows, just a driver figure to add and the finishing touches are complete.

The paint finish is crisp and with no issues. Or bleed between the colours.

If you close your eyes and listen to it thunder past, your taken back to when these machines ruled the world. Just missing that smell.

All in all a great model and if you haven’t purchased one yet, stop reading this and go and get one. The whistle has gone and they won’t stay in the station for long.

Would I recommend - yes
Would I buy again - yes
Have I brought again - yes (different livery and a pre order or 2, or 3).

Excellent model as always from Accurascale

This is my second favourite Class 37 livery, and Accurascale has absolutely nailed it. The Colas colours look superb, the detailing is exceptional, and the factory-fitted DCC sound brings the locomotive to life.
There is a reason why all the Run 3 sound-fitted Class 37s are now sold out on Accurascale's own website. These are simply outstanding models and among the very best locomotives Accurascale has produced.
Running is smooth, the sound is excellent, and the model has real weight and presence. I absolutely love this locomotive. My only regret is not pre-ordering the Lomax version as well, which I really wanted, but my wallet could not stretch that far.
A fantastic model and highly recommended if you can still find one at a dealer.

Fantastic model with great detail. Accurascale trains are simply the best in the business.

Very nice model, fits in well with the rest of my colas fleet. Great sounds!

Superb detail and smooth running. A fantastic OO gauge locomotive.

Another quality loco

I bought five factory sound-fitted Class 37s from Accurascale’s latest Batch 3 release, including catalogue number ACC-154668, Class 37/4 37421 in Colas Rail Freight livery. The decoration and overall finish are excellent, and visually it is a very impressive model.
Unfortunately, this particular locomotive developed a fault almost immediately. The DCC sound cuts out after around 45 seconds of running.
This does not appear to be a controller or dirty track issue. I am using the ECoS controller supplied through Accurascale, and other Accurascale sound-fitted locomotives including other Class7 locos batch run 3 run correctly on the same track. The problem appears specific to this locomotive.
My concern is that this feels similar to sound cut-out issues I have experienced with earlier Accurascale releases, where the sound would simply disappear. I do appreciate what Accurascale are trying to achieve, and when support is available the team do try to help, but resolving faults can be slow because customer support appears stretched.
Based on my experience, I would stillstrongly recommend buying Accurascale models factory sound-fitted if you intend to run them with sound. It is usually cheaper than buying a DCC-ready model and fitting sound separately, and it also avoids any argument about whether the problem is with the model, the decoder, or the installation.
I have learned this from previous experience with an Accurascale Class 55 Deltic, Black Watch. That model ran perfectly well as DCC-ready, but when decoders were fitted, including the ESU decoder supplied for it, the decoders all failed and blew them. DCC plate put back in and ran as normal. I also had issues when trying other decoder options, including a Hornby HM7000 in another Accurascale DCC-ready model. In my view, the issue appears to be with the locomotive’s PCB on that Deltic rather than the decoder itself, and that matter has still not been resolved to my satisfaction. That is why despite sound issues if you want to run DCC you should buy the loco factory sound fitted.
If this Class 37 were being judged purely as a DCC-ready locomotive without sound, I would rate it five stars . The finish, decoration and presentation are excellent. Price untouchable by other manufactures. However, because this is a factory sound-fitted model and the sound cuts out after around 45 seconds, it is disappointing. I would advise caution on this 37 in run batch 3 until Accurascale confirm and resolve the cause of these sound issues. This deserves a five star if the sound was not faulty.

Another fantastic addition from Accurascale. Looking forward to the next run already!

Lovely model, fantastic detail, would recommend!

10/10 for this Colas Class 37 from delivery to track.
Arrived in perfect condition with the detail, accuracy and quality unmatched by anyone else.
The sound is spot on and runs beautifully and flawlessly straight from the box thus credit to Accurascale for this exceptional locomotive.

Excellent paint finish and plenty of detailed parts

This 3rd generation of what is easily the best 37 on the market, is a stunner. Many upgrades from the last batch, working fan, radiator behind the now etched grill and top notch sound file. Absolutely brilliant. Hopefully some 37/7's in the next batch.

What a belter, no problems with this loco. Pipes and plough fitted easily with the buffer beam removable. All on all, just like the real thing.

Cracking model love the livery and sound and a smooth runner as always.

My 1st Colas Class 37, well finished and tuns smoothly!
