Steam - Part 2

In part 1 a conductor pointed out one of two 1,000lb pistons mounted on either side of the engine   towards the very front. 

The first clip is a steam locomotive pulling away from a dead stop. The chuga-chuga sound that begins with long pauses between them then become more rapid as the train gains speed/momentum is that 1,000lb piston head going back and forth forced by steam.
