The Pennsylvania Railroad’s class B6 was its most successful class of switcher or as the PRR termed them shifter. The PRR preferred the 0-6-0 wheel arrangement for larger switchers whereas on other roads the 0-8-0 gained preference. The PRR used road locomotives generally 2-8-0s when larger power was required.The original class B6 was built at the Altoona Works during 1902–1913; 79 were constructed.
