I'm just wondering what this sign is for. It was spotted on a long, high-speed passing siding about 15 miles north of a small BNSF yard in Marion, AR. First time I passed by, there was a maintenace truck near some signal equipment. About three hours later, could not see the truck, but the signs were still there, about 3/4 north of the signal equipment and the end of the siding and the other turnout.
I'll be attaching two images, hopfully! If not, the two signs appeared to be on the far outside of the two tracks. Could not tell if they were double sided, but looking at the images, they may not even be metal! Maybe just cardboard and a very temprorary "post".
Single sign
Both signs
Thanks!
It is a visual signal to inform crews they are entering a restricted area, it is used where MOW forces are conducting repairs or where a temporary track condition requires it.
From the GCOR...
(the BNSF amendment is the usual amendment used by most carriers)
5.4.2 Display of Yellow Flag
A. Restriction Specified in Writing
Two Miles Ahead of Restricted Area. Yellow flags warn trains to restrict movement because of track conditions or structures. To make sure train movement is restricted at the right location, employees must display a yellow flag 2 miles before the restricted area.
Green Flag 2 Miles Restricted Area Resume Speed Flag Yellow [Diagram A.]
Less than Two Miles Ahead of Restricted Area. When the restricted area is close to a terminal, junction, or another area, employees will display the yellow flag less than 2 miles before the restricted area. This information will also be included in the track bulletin, track warrant, or general order.
BNSF Amendment—The paragraph "Less than Two Miles Ahead of Restricted Area", is changed to read: Less than Two Miles Ahead of Restricted Area. When the restricted area is close to a terminal, junction, or another area or if restriction is on a siding, employees will display the yellow flag less than 2 miles before the restricted area. This information will also be included in the track bulletin, track warrant, or general order.

That's what I was thinking but the ones we see around here are a square with yellow over red.

Yellow/Red flags are advance boards for Form B (Men and equipment on or near the tracks) areas. They also are two miles before the beginning of the restricted area. If the yellow/red flag can't be placed a full two miles before, it's location must be specified in writing.
A red flag/board is placed at the beginning of the Form B limits.
