Thanks, yes I did mean Junction indicators, the choice of routes at Salford Crescent have not changed but the signals have where previously there were feathers for routes, now we have Theatre Boxes, still 3 possible routes. It is possible that a 4th route could be added at Crescent, to create Bi Directional running into Salford Central, but that would require new pointwork in an already cramped junction layout.
Unless the next signals are to receive boards with the Letters given at the previous signal as in the west end of Manchester Victoria.
ie, the lines are named Up Salford Fast, Down Salford Fast, Up Salford Slow and Down Salford Slow If approaching Victoria but leaving Victoria they are E, D, C and B.
