The platform extension plans give some clues as to where trains are going to go. For instance provision for 5 x 23m carriages is mentioned for the Clitheroe line, as it hasn't been promised new trains or 170s and the 153s are leaving, that suggests some 158s are heading west. Also mentioned is provision for 3 x 20m carriage trains for the Penistone Line and Leeds-Knottingley-Goole which suggests the reformed 3 car 150s will be based at Neville Hill.
