Starting in 1941 they were converted to class GLCA with changes including AB brakes and power hand brake mechanisms. They were gone by 2-57. Some of these 19th century cars outlasted steam on the Pennsy."
Actually, there were still 730 cars listed in 1957. The last Class GLCA were off the roster by February 1967. These cars nearly outlasted the Pennsy!
