The Connecticut Central started off as a division of the Valley Railroad (steam excursion railroad in Essex, CT) as a means to secure revenue during the winter months. Trackage was leased from the State of Connecticut to operate on portions of the Airline, Berlin Branch and the Valley Branch in Middletown, Portland and Cromwell. In the early 1990's the company was bought by a group of private investors and operated that way until the Providence & Worcester bought them out in 1998.
Businesses served by the CCCL included Stone Container in Portland - now closed (paper products to make cardboard boxes), Primary Steel in Middletown (steel plates and coils), Dyno in Middlefield - now closed (ammonium nitrate for blasting materials), MSR Build Supply in MIddletown (brick products), City of Middletown - now ceased (tanks cars of sewer sludge to Cromwell's Mattabasset plant for disposal). I also seem to think that in the early years they also serviced a fertilizer plant in Portland (Estech or something like that). Cars would be interchanged with Conrail in Middlefield. In the 1990's, CR allowed CCCL to operate all the way to Cedar Hill yard in New Haven. This was due to the fact that CR did not service the Reed's Gap Quarry (TILCON) in winter and had little reason to come north to Middletown. P&W would eventually gain the rights to the quarry and CR relinquished the line altogether. From that point on, CCCL would operate to New Haven under a Form "D" from P&W from MP 15 to Stones (CR yard limits).
The original trackage amounted to approximately 21 miles. The railroad had visions of expanding north along the Valley BRanch to eventiually reach Hartford. Some line clearing had already begun. This was not to be as the P&W bought the railroad before completion of this project. The P&W did eventually repair the tracks to Hartford and, for a short time, interchanged demolition cars with the CSOR in Hartford (they could be seen lined up along I-91 just south of the Charter Oak bridge). This ended partly due to the collapse of the roof of the Murphy Road Recycler's building in Portland a couple of years ago in heavy snow and partly for some legal mumbo jumbo. The P&W does still go to Rocky Hill two or three times a week to deliver cars to a building supply company.
The P&W still usues the Middletown Branch line and the Vally Line. There is also a P&W locomotive fuel/service depot located at MIddletown. Traffic across the river has ceased, at least for the time being.
I'm sure that if I am incorrect on anything or have missed anything that CVRA7 will respond with the information.
