Mount Union was the northern terminus for the narrow gauge East Broad Top Railroad, connecting to the Main Line of the Middle Division of the Pennsylvania Railroad (now Norfolk Southern). The EBT maintained a large dual-gauge yard and coal cleaning plant in Mount Union and supplied coal to the Refractory plants. The EBT ceased operations in 1956 but the track is still in place and owned by the railroad. From 1998 to 2010, the Mount Union Connecting Railroad attempted to reactivate the EBT main track through Mount Union and rehabilitated it, but only a couple cars were serviced and none moved over the EBT trackage.
