The X1 railroad crane was built in 1947 for the Montour Railroad Co. by the Ohio Locomotive Crane Co. and worked on the Montour for 36 years until it was sold in 1983 when the railroad ceased operations. X1 was self-propelled and was used for laying track, maintaining the roadbed, rebuilding hopper cars, and unloading materials at the railroad shops. It carried hooks, a clamshell bucket, and an elector-magnet for many different projects, including ditch cleaning, replacing decking and rails on the Chartiers Creek bridge near Greers Tunnel, and unloading wheelsets at the Montour Junction shops. X1 was often accompanied by car X3, which carried tools and supplies for different types of jobs.
