There are 3...#90, #89, and #475
Strasburg Rail Road maintains four serviceable steam locomotives. Three of the four are in active service currently. These are #89, #90, and #475. Thomas the Tank Engine (#1) also operates at Strasburg Rail Road as its fifth serviceable steam locomotive on the roster.
actually several. the standard gauge ones have 3 operational, there are two 15 inch gauge 4-4-0. if you look around inside the yard you will see a PRR ten wheeler's boiler. a few other engines are sitting there.
