Yellow Beast II

I found this monster near my home in the harbor of my town. It's a Ballast tamper, used to build tracks and repait old ones. This beast is nearly 40 tons heavy and can build almost a mile of track in an hour.
While I was shooting, the operators arrived and asked me, what I do here. After I told them, that I'm not gonna steal it, they turned out very friendly and explained everything to me.

I hope, you like it!
