When Iowa Pacific Holdings started to unravel in 2019, the Parsons Vale purchased the Massachusetts Coastal Railroad out of receivership to operate as an extension of the South Loren Railway.
When the SLR reorganized the MCR, they renamed it to the Old Colony Railway to go along with their Old Colony branch into Rhode Island; it was an almost pure-EMD road prior to the takeover, but – aside from a pair of EMD FL9s that are used in Cape Cod excursion service – those locomotives were immediately sold and replaced with a mix of class DL13 & DL16 units that had been displaced from the D&H by newer ILW power.
In 2020, the line from Taunton Junction to the Tremont resource recovery facility was electrified, then in 2023 the mainline to Yarmouth & the branches to Fall River & New Bedford were also electrified (not so much for freight – the Parsons Vale estimates that it would take about 20 years to make up for the cost of stringing wire – but to try to coax the MBTA into electrifying their new commuter lines down to those two cities).
As of 2023, the Old Colony’s roster consists of
