Freight trains in the US are so much more than A to B and switching, I’d love to see a route and services where you have to pickup and drop off of the same train, perhaps back into different industries and spotting cars etc. Then returning to a yard. North American freight is desperately in need of this variety as it happens so much in the US. I’d suggest possibly conrail shared assets or something Norfolk southern, csx in Miami etc.
I know the UP mainline here runs a few locals to serve local industries, would be nice to actually have a route with local trains, as it gives activities to do outside of A to B runs.
These kinds of activities are quite common on TS. I'm thinking particularly of a couple of Norfolk Southern routes. Be nice to have that railroad in TSW2.
