Are there ever occasions during planned or unplanned service
disruption where an LU train heading say "eastbound" will require to
finish its journey in the "eastbound" platform of a two-platform
station, pick-up intending "westbound" passengers for the next
departure whilst still on the "eastbound" platform then head
"westbound" on the "eastbound" line in order to access a crossover to
the "westbound" line?
