Was looking at trains which might be going via Hebden Bridge today and spotted 3S08 as linked below. I wonder what's Wigan L.I.P. and what exactly is this train? Some sort of NR test train which they run from time to time? I guess that's what is meant by "This schedule runs as required". I guess it stops in HB to switch back to Rochdale way.
