Some locos "escaped" (it was still powered on) from a station because the driver (totally not me) got ran over. I managed to find two of the same locos (not sure where the second came from) several km away from the station , and I managed to return them without incident (trust me totally nothing went wrong)

everything normal...

(don't mind me just some uninsulated IC2 wires)

aaaand the trains ran away again (managed to break the track at the next station, which coincidentally was the station where I'm supposed to return these rainbow locos)

Finally, after an hour of "very smooth progress", I finally accomplished the task of moving 2 locomotives from one place to another! With~~(out)~~ incident, of course
