Off on a siding

When trains switch off onto a siding, how does the crew know if they are completely off of the main line? Are there sensors that let the dispather know that the track is clear?

Modern day engines are generally equipped with footcounters which, while not always accurate, help to determine when you're in the clear. Also, most engineers know what fits where, if you've got a 7,500 feet train and go into an 8,000 foot siding, you know you're clear.

If the territory is under CTC control then the track circuits will indicate to the dispatcher if the train is in the clear. If the train is not in the clear then the CTC computer and the local interlock circuits will not allow the dispatcher to move the switch or line a conflicting movement. The data to and from the dispatcher is transmitted by wireline and/or radio.

....and if the siding is not a passing siding, Mr DERAIL will make sure you don't foul the main track at the other end and that the guy that was supposed to be protecting the shove gets an unpaid vacation.[:D][:D][:D]

And if you're still in doubt... somebody gets to take a walk and find out.
