Oh Boy! Railroading at it's worst. The removal of the caboose meant new rules, Leaving main track switches open in dark territory was one of them..... Having the next train stop or section crews line a main switch back normal is foreign to me.
Scary stuff for sure...
Having CTC suspended is something I've never run across....
Leaving a siding switch open after a train leaves a siding is one thing but leaving an main line yard or service track switch is another story.... This switch was not a siding switch , It would be a power switch.
