Restricted Speed is either 15 or 20 MPH depending upon the carrier - prepared to stop within 1/2 the range of vision for obstruction, broken rail or train ahead.
Sorry, I have to correct this. It's looking out for broken rail, not stopping prior to. You have to stop prior to other train, obstruction, or misaligned switch.
And I said it 1000x times before, but I alwyas repeat it: restricted speed is not a speed, but a METHOD OF OPERATION.
