I have fitted the Dublo present day Scotsman, initially with the A1/A3 Flying Scotsman profile, but after discovering that that one has the second whistle and bell for the US tour Scotsman, switched to the basic A1/A3 profile. I used the second largest speaker housing, no power bank. That fit perfectly. I also fitted the Accurascale Deltic, using the largest speaker housing, and it all works perfectly. Only issue is that the HM7000 decoder can't access the hallway light on the Accurascale model, which isn't a big deal with me. All the other functions still work. Now that I know that they gave us a profile made for the US tour Scotsman, I will be fitting mine (I have the slightly older 2013 model that came with the observation car).
