| Here is a photo from page 737 in the "Centennial History Of The Pennsylvania Railroad Company: 1846-1946" that was composed by George H. Burgess & Miles C. Kennedy and published in 1949. Photo Caption: "Class T-1, the fast passenger locomotive with four cylinders. These engines, placed in service in 1942, are the successor to the S-1 ~ the first four-cylinder locomotive to be built in the Pennsylvania's program of developing multiple-cylinder engines." Shown here is PRR engine #6110, a T-1 (4-4-4-4) "Duplex" built by the Baldwin Locomotive Works during April of 1942 and retired in December of 1953 after just 11 years of revenue service. |
