Signals & Track Spirit Of Steam Custom Timetable Problem

i am trying to make a new timetable for spirit of steam but the signals at lime street wont let the train past
the signal ls_ds12 will not change to green for a light engine move to couple onto some coaches at platform 11

 

Have you set the call on dependency on instruction 2 of the train coming in, allowing it to move into a block where there has been an active train? It will be in a drop-down at the bottom of the details pane for that instruction?

 

tried that and re simulated same problem,,,

 

okay i have it getting past the signal now using go vias before and after the signal. might have a new problem with formation ends now though
