There was what might be called a directional or route-indicating signal at Banbury South, where the Down Loops terminated and Banbury Loco came in. Here are some pictures from the files:
Heading south past the gasworks on Friday, 27th June 1958, is Banbury's Churchward 2-6-0 No 5306 with a train from the ER. (see Banbury Expresses for details).
"King" no 6014 King Henry VII comes out of the mist at Banbury South with a Down express on 29th April 1960 (see Banbury Expresses for details). 3845 is waiting to come off shed.
Two closer views of the signal with the levers for several indicators. Photos author's collection.
