Morning Paul,
I agree with your Class 37 thoughts. Bachmann's model is good and as your say, little to separate that and Accurascale.
Mine is also DCC ready but probably will fit sound in due course. I've heard/handled too many noisey ones in the shop not to !
I'm also no expert but in a way that's quite liberating as I work on the basis of if it looks right...etc, etc...
I think the finish on Bachmann's green is better, deeper. I'm also on the fence regarding their treatment of the windscreen and how it fits to the front of the cab. Two areas where the Accurascale is clearly superior to Bachmann's example is that of fitting DCC and price. For a retailer, Accurascale always sells at full RRP, whereas Bachmann is sold at a discount. Taking this into consideration, that puts Accurascale's DCC ready model some £50 cheaper that Bachmann's. Good for the customer as well. DCC fitting is a case of unclipping the roof whereas Bachmann relies on body removal.
Detail wise, there is little difference between the two as there is in terms of running etc.
Now, do I note a TT120 Shelfie.......?
