CSO doesn't really serve New Haven area customers, but they instead haul CSX's traffic for them between Springfield and Cedar Hill. From there, CSX serves various customers in and around Cedar Hill. I would say the majority of traffic is generated from within the yard itself, where Circle of life runs a very large C&D facility, Metals Management has a large scrap metal yard, Anastasio has a steel and lumber reload center and Transflo has a decent sized transload terminal where they handle both liquid and dry bulk products. There is also a small cluster of customers on the Amtrak line just a bit north of the yard and there's maybe 2 or 3 customers left on the corridor south of New Haven, with the biggest being another C&D shipper, City carting at Milford. PW uses a couple tracks in the yard for power and car switching/storage and they run a couple locals out of there, including some decent sized stone trains through the area which mainly head south on the corridor. From what I understand, there is only the occasional interchange between PW and CSX, as the majority of that takes place in Worcester.
