Western Railroad Discussion > HLCS on Railroads

Does anyone know if other Railroads are using hyrail warning device for MW, Signal personal
besides BNSF?
BNSF invested heavily in a program that warns Dispatcher and Individual Hyrail vehicles if they
exceed there authorize limits, are on the wrong tracks and when there within 1 mile of authority limits.
The dispatcher also can pull up a screen that displays on the hlcs vehicles that shows milepost location,
mph speed of vehicle, thumbwheel setting, track warrant or track and time number associated with vehicle.
It's a system that's saved life's and works very well.
Wondering if other Railroads use a similar system.

Explain a "thumbwheel setting."

I believe the Alaska Railroad has a similar system running...I don't believe its systemwide yet, but its being slowly rolled out along with the system that will operate the future Positive Train Control system.

There's a small thumbwheel dial on the upper right of the HLCS control panel that allows the operator to set for N/A, Main, Main 1-Main 5, and Siding. This is part of the safety feature to ensure the operator sets on the correct track as requested.

So thats why they say "opps hit the thumbwheel" when the DS asks them why they are out of their limits.
