UP's track gang, which is working on replacing ties at the east switch of Rocky, has cleared the tracks to allow the morning Zephyr to creep through at 15 MPH. The foreman of the track gang has established was is known as a Form B. A Form B has starting and ending limits, and when active, a "red board", which is literally a red square board on a pole, is placed trackside. Trains are not allowed to pass the red board, regardless of block signals, or even dispatcher permission, without getting permission from the track foreman to enter the limits.
