It's unfortunate they are going to be starting this project just as the traffic at the station increases for the Hartford Line. In the end I'm glad its moving forward, but I think an 18 month timeline, as suggested by the potential contractor, is probably more realistic. I think only Amtrak trains are planning to be stored overnight at Springfield, the CTrail trains will all layover in New Haven - the first southbound CTrail departure from Springfield isn't until after the first northbound train arrives. Lack of space I think is one of the reasons that more CTrail trains are not serving Springfield. Eventually I believe they need to build a Springfield layover facility to store trains overnight in order to expand service further.
