| With Raymond Loewy styling and an unusual wheel configuration, this Pennsy duplex is a rare loco. Built in 1945 by the PRR Altoona shops, it had 80" drivers, 300 psi, and a massive engine weight of 502,200lb but produced a respectable 64,653 lb tractive effort. According to Steamlocomotive.com "According to most sources, the divided drive proved to be a major maintenance headache, however, because no way could be found to stop one or the other driver-cylinder set from slipping, either starting or, more alarmingly, at high speed. This liability proved fatal to the chances for real success for these engines, and they were retired well before the much earlier vintage K-4 Pacifics." This one was scrapped in 1953.
