Has anyone suggested the Harford Line? It's an 1 hour and 24 minute route from New Haven, CT to Springfield, MA. The route also 9 stations including a stop in Hartford, CT. It will bring the P42 genesis into TSW 2. Plus there's potential for CT rail for commuter service.
Bring it on and the return of the TSW 2020 classic Metroliner Cab Car and will change NEC Boston route with P42 appearing on lakeshore limited route
I did a write up on it about a year ago. I think it would be a good fit. https://forums.dovetailgames.com/threads/the-hartford-line-commuting-in-connecticut.68488/
