The Pennsylvania Railroad’s steam locomotive class D5 (formerly Class G pre-1895) comprised eighteen lightweight 4-4-0 locomotives for light duty maintenance-of-way and branch-line service constructed at the railroad’s own Altoona Works during 1870–1873.They shared many parts with other standard classes although less so with the heavy 4-4-0s on account of their lighter build; instead they shared some components with 0-6-0 switcher classes F and H (later B1 and B2).The Class G locomotives had a straight-topped boiler unlike the wagon-top of the other 4-4-0 classes.
