The line was embargoed due to poor track conditions in 1999, and was formally abandonded, I believe, in 2004. To the best of my knowledge, the track OUTSIDE of the industrial park still belongs to Pan Am Railways (Springfield Terminal). After doing a bit of research yesterday, I identified three possible customers, and found two more that I couldn't identify. They all have rail spurs going to them already, and they all look to be in pretty good shape (probably because they haven't been used in years).
The potential customers I identified:
Sweeney Transport 2073 Westover Road
Biy Y Distribution Center 2189 Westover Road (may have originally been the Stop 'n Shop Distribution Center; Anybody know?)
Engineered Polymers 2323 Westover Road
Unidentified Logistics Drive
Unidentified Champion Drive
I'm just guessing here (and maybe engaging in some wishful thinking), but there are a number of reasons why I think the Westover Branch is going to be Rehabilitated rather than torn up.
1)Rebuilding of the Conn. River Line is due to begin this year. The project (Springfield to East Northfield) is projected to take two years.
2)The interchange with NECR at Miller's Falls in almost rebuilt, while the connection with the PVRR here in Holyoke is due to be done this year. There is also the possibility that the old B&M freight yard at the end of Dwight Street will be partially rebuilt this year.
3)Forestville Lumber in Plainville, CT. Unless I'm mistaken, this customer stopped receiving rail shipments for at least a year. I base this on the fact that I moved to Holyoke in May of 2009, and saw no centerbeam cars on Pl-1 until January of this year. If I'm wrong about this, or if anyone has more details I'd like to know.
4)Norfolk Southern. It seems incredible to me that NS would go into the PanAm Southern venture with the ONLY object being reaching Boston. It makes sense that the NS influence on PAS will cause them to aggressively go after new business (and getting back old Customers).
5)The only reason that Guilford lost so many customers during the 90s, was due to things like late shipments, damaged product, etc. which was generally due to deteriorating track conditions due to lack of maintinence. With the exception of branches like the one in Chicopee (which from my inspection of it will need to be entirely rebuilt), PAS is getting their mainline track rebuilt for free. This can't help but attract old customers back (C&S Grocery Warehouse in Hatfield), or gain possible new customers(Coca-Cola in Northampton, which wanted a spur built to their new facility in the mi-90s, but the City of Northampton wouldn't let GTI build the spur unless they ALSO (at GTI's expense) build a tunnel under the tracks to connect the two bike paths). This wouldn't be a factor, as a tunnel will be constructed as part of the rebuild.
