*  Route via shunt signal 149

The symbols labelled 48 and 49 on the track diagram represent "Limit of Shunt" boards.

The Down end of points 523 is a single slip off 524 crossover and so there is no facing connection from Up Fast to Up Goods here. Therefore there is no route from 151 to 91/92/94 or from 124/123/137 to no. 49 Limit of Shunt board.
