On the evening of October 10, 2013, southbound CSX stack train Q156 experienced traction motor issues involving its second locomotive, CSX AC6000 5006 after departing from the siding at CP 43 in Fort Montgomery, NY on the River Sub. After the conductor contacted the mechanical department, it was discovered that the fifth traction motor was not working properly and would needed to be cut out. The following morning, we returned to CP 43 to find 5006 paired with an AC44 sitting on the siding. RJ Corman derailment services showed up shortly after our arrival to change out the traction motor; a true sight to behold. Very cool to watch!
