                      Concrete Bob - cracking loco

                      After travelling behind the real loco at Bo’ness last year, it became one I wanted in my fleet. The Accurascale loco captures the modern details found on the DRS class 37/4’s perfectly, nice level of lighting and smooth, quiet runner. I must add my thanks to the team at Accurascale for helping me get this loco for my fleet, it was very much appreciated.

                      Utterly brilliant model! 👏

                      Highly recommended model. Stunning


                      A Fantastic model

                      Brilliant 37425

                      Lovely model and smooth runner.
                      Opted for a non sound version of this particular model.
                      Can’t wait for my other sound fitted models on order.

                      Great Loco

                      Really pleased with the quality of the loco and the factory fitted sound is supurb. Just need an original Class 37/4 doing in Regional Railways next.

                      Another amazing addition to the range

                      Ticks all the boxes, one of the very best models on the market right now

                      Fantastic loco.

                      After buying 37423 and seeing how awesome it was I couldn't resist buying another 37. 37425 is just as impressive. Great work guys!!

                      Incredible model

                      I had already ordered three Accurascale 37s but these are currently on the way. Having seen the superb detail and other reviews of the first batch of 37s to arrive, I haven’t been able to wait. So 37425 was ordered and has become the first of my 37s to arrive. It is quite simply a stunning model in all respects

                      Class 37. 37324

                      This is a very nice model, and excellent value for money. The only reason I have not given it a 5 star review is that the The roof fan grill on my model was not attached to the model on one side, in fact it was completely detached after trying without success to fit it correctly, I have now with the help of a spot of super glue managed to get it to fit, but not what I would call any where near perfect

                      Paul S.

                      Great model. Best 37 ever.
