Conrail's Marion Branch was the ex NYC Michigan Branch that ran from Elkhart, IN to Anderson, IN. This line was an important line to Conrail, enabling them to get automotive traffic from Michigan and Northern Indiana down to Indianapolis and Avon yard. The line from Elkhart to Marion, IN is signaled with PRR CPL signals, making this the only NYC line to have PRR signals(came from the PRR Richmond branch when PC rebuilt the Marion branch back in 1973 or 74). From Marion to Anderson the line was called the Dow Secondary and was dispatched by Form-D's. This branch was also home to Conrail's unique SD80MACs and later on the SD70MACs.
