Kirkby or Southport to Blackburn have nothing on that late turn which was Blackpool-Blackburn (via Todmorden for those who don't know the area) - 2hr 51 end to end, then six minutes (if on time - never happened) to change ends and come back to Manchester Vic which was another 1hr 10+.
Southport to Leeds via Elland will be nearly as long.
