But it can play choo_choo.wav if you want.

I actually got to ride one of the steam locomotives in a heritage railway in Connecticut. The Essex Steam Train uses a China Railways SY class 2-8-2. There's another one in New Jersey as well. The stuff made by Tangshan Locomotive and Rolling Stock Works is interesting because it produced the last steam trains in the world that were built for non-tourist purposes. Hopefully China sees the historic value in preserving them and keeps some in a functional state for the long term. They apparently have one heritage railway, the Tiefa Coal Mine System, with a couple of the steam trains still running for tourists.
