Steamtown no longer has steam trains. 
They have a mall now, though...

They are all down right now, but not forever!
In order to be fixed
1st (currently): 1929 Baldwin Locomotive Works #26, an 0-6-0 switcher
2nd: Boston and Maine #3713, a Lima-built 4-6-2 Pacific-type. That sucker has an oversized firebox and superheaters that are able to pull and heat a 14-car passenger train at track speed. Woot!!
3rd: 1923 Canadian Pacific #2317, a 4-6-2 Pacific-type heavy passenger locomotive, which they will use as their mainline passenger locomotive.
