Sometimes home signals at an interlocking might not have an approach indication but they would also have a square end on the blade. Doesn't look like an interlocking here anyway. Maybe somewhere in New England?

Author: ExSPCondr A bunch of this type of ABS + Train Order type of operation only had signals that could display yellow aspects at the beginning and approach to sidings. This saved a bunch of line wire and relays, as it only took 3 wires to run the system.
The only disadvantage was when following another train, the signal leaving the siding would stay red until the preceding train cleared the home block of a signal that could display yellow, which could be the approach to the next siding... A broken rail would also make you flag several blocks. The SP's Phoenix and Siskiyou lines were that way, which cut costs considerably, as they were lower quadrant semaphores which couldn't display yellow without a second blade. G |
