This signal box was east of Polmont station on the north side of the line. East of the station a long siding on the south side of the line was converted into a loop and a bay platform single track was added to the east end of the eastbound platform.
This box replaced two older boxes: Polmont Station and a temporary Polmont East.
The box closed in 1971.
