Red and Yellow sings...

Also known as "flags" (on at least the BNSF), they stand for two different things either happening, or about to happen. The simple square 'yellow' flag is two mile notice of a temporaray speed restriction. It would then be followed by a green flag to indicate the speed restriction's end. If that flag was yellow over red, it would mean a two mile notice to a MOW crew that had authority to work on a section of track. The red flag was simply the start of the MOW authorization of territory they were working in. Trains would have to make contact with MOW Foreman in charge of the work zone to proceed through that area, recieving special instructions on speed and the like.

Hope that helps....
