Branch remained intact and active as far east as East Millstone to a rubber reclaiming facility located at the end of the branch until 1972 when the branch west of Clyde Road was abandoned. PC wanted to abandon the line but was required by federal law to serve any customers who wanted rail service regardless of profitability. During the first six months of 1972, PC delivered only six carloads to the rubber factory, earning $1,383 in revenue; the cost to PC for making those deliveries was $3,862. PC filed for bankruptcy in 1970, and sold all railroad assets to the new government-created Conrail (CR) on April 1, 1976. PC only sold the portion of the Millstone Branch up to South Middlebush Road to CR while retaining ownership of the South Middlebush Road–East Millstone section. In 1971 several warehouses were built along Clyde Road, three of which had rail spurs installed and connected to the line. However, only Hermann Warehouse Corporation utilized rail. One of the rail spurs has since been removed, never having been used. Trackage west of Clyde Road to the East Millstone terminus was abandoned and removed in summer 1980 (a small section of track remains buried in brush William and Market Streets in East Millstone). Motorists complained that the poorly maintained grade crossing near Colonial Park was causing damage to their cars. By this time, there were no active customers past the Route 27 crossing; the branch fell into disrepair and became overgrown with vegetation. For the next 30 years, the line west of Route 27 remained active to provide service to Hermann Warehouse Corp. CR upgrade the remaining infrastructure, replacing ties, switches, and brush. New ballast was also laid. Present conditions After branching off Amtrak's Northeast Corridor at County Interlocking, the Millstone Branch begins with the use of NJT trains terminating at the Jersey Avenue station. Track currently ends at a point between Clyde and Dahmer Road crossings. In 2001 three luxury homes on the outskirts of East Millstone were built on top of the right-of-way that borders Colonial Park. In 2006 a new housing development was built west of Dahmer Road; backyards and driveways of several houses were constructed on top of the former roadbed. The bridge pillar in the middle of the Millstone River which was intended to carry the tracks to M&S still stands. The engine house and wye track in East Millstone
