After the closure of Broadstone (year?) didn't Westland Row become the terminus for all former MGWR services? I'm a bit sketchy on this period of Irish railway history, but was this because it wasn't possible for these trains to get into the main body of the station at Amiens Street?
Anything coming Up the old MGWR ran in from Mullingar via Enfield to Drumcondra Jct.
At that point they could take the right had line to Newcomen Jct, or deviate left towards Ossory Road Jct.
At Ossory Road you joined the GNRI main line and could access the terminating platforms at Amiens St (Connolly).
If you came via Newcomen Jct then you could only access the through lines (DSE lines) towards Westland Row.
At some time in the 70s Galway and Westport trains were diverted to Heuston from Athlone via Clara, Tullamore and the GSR main line and thus did not run via Enfield.
The layout of Drumcondra means that coming from the former GSR, you have to run via Ossory Road Jct and North Strand Jct.
In those days There was a greater separation of trains north and south at Connolly and thus the terminating platforms would have been fully bused by suburban services.
Galway and Westport trains thus ran to Westland Row and then ran forward to the carriage sidings south of there, but I cannot for the life of me recall what they are (were) called.
For (I believe) historical reasons the 1805 Heuston to Westport and the 0745 return was worked by a brace of 121s right until nearly the very end. This was the ONLY booked 121 passenger work over the GSR, apart from VERY rare sojourns.
One I particularly recall was a Rose of Tralee contestants special which was worked throughout from Heuston to Tralee by a brace of 121s with a Cork Driver. It ran non-stop probably one of the very few non-stop, and certainly the longest 121 working in the Country. Naturally your truly was on the footplate the whole way
In the mid 80s for a period the Up Cork Mail was a booked 121 job (sometimes a worked by a pair). Never managed to grab that job though.
Non passenger 121 workings on the GSR were restricted to the North Wall to Waterford F/Liner and return working. I was very lucky one night to grab a shot of that working from the cab of an 071 working the 1730 Cork to Heuston high speed service as we passed at about 165 mph near Hazelhatch.
Happy days.
