Looking at my 1992 WT it strikes me that I can only find a single pair of explicitly timetabled ballast workings. One empty train departed Athlone 07.25, arrived Portarlington 08.29, departed Portarlington 08.41, arrived Lisduff (quarry) at 09.35. The return laden working departing 11.15 and arriving in Athlone at 13.55.
Is this the only timetabled working of a ballast train or have I just missed others?
Why was this particular working timetabled?
Did it always run?
Was the train unloaded in Athlone or just stabled there for use elsewhere on the network?
Cheers!
