the HSP46 locomotive or also called the MPI is a diesel electric locomotive used by MBTA and are on almost every MBTA line including the Boston To Providence line, and started service in 2014 Cab of the HSP46 locomotive HSP46 in South Attleboro I think this locomotive would be great for TSW2 as it would add more variety to the already busy Boston providence route adding more variety equals being less bored, having both the F40PH-3C and HSP46 together would mean all around more MBTA services for the game
Excellent idea and better yet bundle it together with Avelia Liberty as the NEC 2021 pack. The Avelia Liberty will run like the Class 801 on Train Sim 21 ECML South Peterborough London King's cross. HSP 46 does commuter run.
