We haven’t researched the full service career of the T1 fleet, so we can’t say for certain how often it happened, but the answer is definitely yes. 25 of them were built at the Baldwin Locomotive works in Eddystone, PA, just south of Philadelphia, and there are references to one being displayed at railroad equipment shows in Reading PA, and Asbury Park, New Jersey. T1 #5542 was assigned to pulling train No. 17 between Broad Street Philadelphia and Pittsburgh station at least once. However, there was little need for the T1 to run east of Harrisburg, as that region was electrified, and blue ribbon trains were serviced by the GG1.
