This looks like a heavy travelled main line.... Double track and electrified... Having a derailed car sitting on the main ties up one of the main tracks.(maybe both if the car is just clear of the other track. Not good for business.... Yes I know it's possible to re-rail a car with blocks, re-railers hydraulic jacks whatever but you have to get them to the site first . You can't always drive to the location., also needed is a engine to move the car over the re-railers. so that means getting rid of parts of the train, Why? hanging on to 40 or cars trying to make a gentle move is not that easy. If the car is loaded it also makes it a little more difficult. It seems the big hook was handy so they brought it out only to unload the blocks of wood etc....Yep a little over the top,but hey it's their railroad.
