For me I have been loving a lot of what has been offered The last 3-4 years.
036 curve rated CN diesel legacy and would love to see more like the H10. Tons of features that can navigate 036 curves. Would they / could they fit cylinder steam and whistle/dynamo steam in a 036 rated locomotive? May creep to vision line but would like to try and get those features in a 036 locomotive. Like maybe a USRA Pacific.
