After the IRM "A" class comes out. There is no doubt in my mind that the "C" class which could be 2-3 years away makes the most sense to do a run of. MM has already elaborated on what he is planning on doing in the next 2-3 years in the realease of those anticipated re-runs like 201s with new liveries ect. So really by the time all that has realsid, I reckon enough time will have passed to look at GM 141/181s again. However there are still designs like the Sulzer diesal, steam loco, G class.....or even a turfburner! That could be looked at before such a re-releasing models that have a decent model with somewhat adequate numbers already circling about. I would love a 141 and too strugle to find one decently priced and the right livery when funds allow.....but when C class and sulzers are yet to be modeled.....I don't think anyone will be in a rush to release them
