The issues with the switches at NHP and Freeport is for some reason if you went in the clear there, the tower wasn't able to verify this on the board. This would result in train orders having to be issued. There was one instance at NHP a few years back where a freight went in the siding with the whole train, holding the main, and a westbound was given a signal behind them. I'm not sure what aspect that train received, but if it wasn't for the quick thinking from a brakeman that was standing at the switch, that switch would have been run through.
When we used to switch Chesler Plywood, there was a good slot to switch them at night where you could hold the main. At that time, there was no rundown on the lock - it opened right away! Again, things may be different now. Yes, TC driver is correct that if you hit the pedal, you reset the timer.
