On a sunny, freezing winter morning, Atlanta, GA to Croxton, NJ intermodal 212 splits the MP 21 automatic signals at Shamrock Station on the Reading Line with three AC-traction GEs out front. This train must have had a record run, making the trip from Atlanta to Reading in only 23 hours with work en-route, compared to the 24-25 hours that same section used to take with stops for crew changes only.
