A westbound coal empty approaches the 80th Avenue grade crossing and the east switch of Leyden on a beautiful fall morning in early October. If you look to the right of the train, you will notice a sign with two red triangles and two yellow triangles. This is called a "yellow/red board" or "yellow/red flag", and it informs crews that they are two miles away from a "red board", which is a similar sign that is solid red. Trains are required to stop at a red board (regardless of signals or even the train dispatcher) until they get in contact with the track foreman that is responsible for the red board. In this case, the red board two miles down the track is protecting crews that are installing new "quiet zone" grade crossings in Arvada.
