I will revert when I've had a chance to run my A12 loco but what I have seen so far in terms of presentation and packaging and the model itself, is in my opinion really excellent. I cannot claim to have ever driven an A Class Metrovick loco but did once have a short turn at the controls of a AR locomotive many years ago in Sligo, and have walked through the engine compartment of a B201 class, which had just arrived with the Saturday early afternoon down train from Dublin. For the IRM Crossley era models, I look forward to a Crossley engine sound package becoming available in the future.
