The 1973 time is for a train stopping at all open stations between Nenagh and Limerick, so stop Birdhill but not at Castleconnell since it wasn't a stop in 1973
The 2009 train of course has a massive acceleration and braking advantage by at least 20% over its 1973 cousin
Back in the early 1990's Limerick to Ballybrophy was 1 hour 17 minutes, and thats twice the distance of Limerick Nenagh
