The class D15 (class T, pre 1895) of the Pennsylvania Railroad comprised a solitary Lindner-system cross compound steam locomotive of 4-4-0 "American" wheel arrangement in the Whyte notation. The sole locomotive was #1515, built in 1892 at the PRR's Altoona Shops, it had very British lines with a full-length footplate, splashers, a six-wheel tender, and large 84 in (2,134 mm) drivers.^[3] It was built in 1892 by the PRR's Altoona Works, and remained in service until it was retired and scrapped in November 1905.
