BR 45 1-Co-Co-1 No D104 down express' leaving Leeds Central in the late 1960s. With a split headcode LMR Peak in the view I did suspect this was whilst Leeds City was being re-built rather than a Kings Cross train but 1N13 was the headcode for the "White Rose" and is presumably departing for Harrogate?
