Aspects shown in rules 9.1.3 through 9.1.8 and 9.1.13 may be displayed on signals with or without a number plate on signal mast.

Aspects shown in rules 9.1.3 through 9.1.8 may be displayed with a "D" sign on the signal mast to identify the signal as a Distant Signal. When a "D" sign is displayed, if a train is delayed per rule 9.9 or 9.9.1 between Distant Signal and the next signal, proceed to stop short of next signal.

Absolute signals at automatic switches, outside of block system limits, convey main track Distant Signal information for the other end of the siding.
