Western Railroad Discussion > Blue light and loud speakers along the UPDate: 05/15/21 17:09 Blue light and loud speakers along the UP Author: DanCM One thing I forgot to mention in my post about Moffat Tunnel Sub, there were every so often I passed a pole that has a blue light and loud speakers. I assume these are for security but dont know. Just what is the blue light and speakers for?

Blue Light might possibly mean a train is approaching from the tunnel. Ben Date: 05/15/21 19:22 Re: Blue light and loud speakers along the UP Author: DanCM radar Wrote:

They have them in different places throughout the route Blue lights or flags are normally used for worker protection. It is hard to say excactly what you are seeing without pictures, a better description or someone who knows the territory.

Intended for use by the dispatcher to contack MOW folks who might be working there. Jeff

There's a on/off switch at each location, usually on the signal house/box. I don't know how early they come on when the system is active. I've only seen them working from the cab while passing through control points on trains. Many in my area seem to have been deactivated. |
