Hi, this goes for any gauge, but you need some serious tools to do it, I know your hand is the most common use to fix the problem but just think how it's done with the prototype, the problem with videos its sometimes in a foreign language and in this case: you guessed it: German but the stages how it is done you don't need to understand what they are saying.
What I can't understand nobody has produced a hydraulic lifter in 1:87. (lol)

I hope you enjoy the video, so the next time your loco derails you know what to do, pick it up with your hand

This is exactly what I want to use my crane train to do (in my case pretending the little Robel has the capabilities)... shut down the segment (reroute other traffic if possible) - and send in the crane. Once the crane is there THEN I'd use my hand to pick it up and rerail/fix.
