Its pretty neat watching them get up on railroad cars and jump from one to another while digging them out, they also have an elevated platform that they get miniature excavators up on them too and they have platforms they sit on and they grab them and swing them in front of them as they move.
I used to work for a Komatsu / JCB dealership as a field tech and got the opportunity to work on these backhoes when they broke down on top of the rail cars, needless to say it is not fun in the least to have to crawl up and down and work on these when there is a railcar full of derailment debris and lots of rebar sticking up all over the place.
You get over the cool of it all real quick at that point.
