I bought this sound fitted version and it is brilliant as usual from Accurascale. The details and finish is amazing. The cooling fan and the sound is like icing on the cake. I bought this loco together with set of coaches and runs beautifully.
Another excellent product from Accurascale.

Superb detailed model complete with excellent sound file, looking forward to batch 2,3,4 👌

A highly detailed model with lots of detail I have the sound version which is very realistic. The box packaging and manuals make this model stand out from its closest competitor.
My only criticism is that the cab lights are to bright, and there is no engine room lighting unless i have overlooked it. Apart from that it is a massive leap forward from the old problematic Hornsby super detailed 31… keep up the good work, very impressed. If only they were this good when i worked on them, we dreaded them an AEI was far superior.

The model is full of detail and the sound is amazing. A smooth runner and a perfect match for my Accurascale Siphon G newspaper vans.

Well that was well worth the wait, there is so much detail on this 31, my two favourite parts are the cab steps and the front end detail it’s so finely moulded it’s wonderful, just need the MK2c’s to go with it and it will be complete!

Been worth the wait another stunning highly detailed model from accurascale. Perfect in every way. Front view is just awesome just like its main body - Love the livery and a tops number was my time period so will always go for these.

As I am sad enough and old enough to have logged 402 on several evening commutes labouring northwards at full thrash from Gasworks Tunnel on the climb to Finsbury Park and beyond, this model was a must have and does not disappoint. Simply splendid.

Another excellent model. A great shade of BR blue!! Looks just as I remember. Sounds good to!

Accurascales best diesel model yet. A smooth runner, fantastic sound and great detail.

The recent arrival of my "gargoyle" was the end of a timely anticipation filled wait.

The locomotive is fantastic, dripping with details and looks the part. The details are so plentiful the loco was found to be literally dripping with parts. Like Sam's Trains, my loco had not one but two cab individual access steps come adrift during transportation. I reattached the wayward steps to their correct locations and the beast has now entered service.
Due to the slight blip mentioned I have deducted a star on this occasion.
I am also concerned about the access "covers" on the base of the bogies to protect the driving gears are only held on by delicate fragile clips. This is a bad design and more robustness should be incorporated within the design.
The locomotive is now a regularly rostered unit on my 5 coach regional services.
