I can’t help thinking the Class 185 DMU in both 00 & N gauges would suit Revolution perfectly. Only two main liveries, which you seem to prefer than offering multiple versions. It complements your N gauge Mk5 TPE sets, Pendolinos and forthcoming 175’s and 180’s in various locations across the North.
Requests for the 185 crop up very frequently (see Accurascale’s new model request thread). Accurascale (rather bizarrely,) have discounted tooling them, as the potential transfer to Ireland for re-gauging didn’t happen.
I think the biggest obstacle to them being produced seems to be the ‘Chinese Whispers’ that another manufacturer is already working on them!
This seems to be the case with various multiple units at the moment - Electrostars, Class 120’s, 313/314/315’s, 153’s all have rumours floating about (as did the 320/321’s for seemingly ages, before Revolution took the plunge and announced an 00 version).
So how about it Revolution?
