As a Famous Train Buff on the Metro North, I would love to see the M3's/M3A's in TSW. But there is one problem, and that is running them. The throttle isn't just like an M7, in which you just move it. It also has a deadman/Spring feature, which when you let go of the throttle it will lift up with the support of a spring. Unless Dovetail wants to switch game controls, Its the only downside of running with M3A's/M3's. Everything else about them is great, and overall would love and beg Dovetail to add them to TSW. But I would love them on the MNRR Harlem Line in TSW.
