I wouldn't get too excited though. I used to have a great sense of expectation every year coming up to the new timetable because I had some kind of misguided notion that in return for millions of euro for track renewal, new rolling stock, resignalling and level-crossing automation that they might manage to shave 5 or 10 minutes of the Longford - Dublin running time.
Now, in fairness we do have more services so I suppose that is progress and they took 10 minutes of the 7ish AM Longford departure by making it an express, but that is the only progress I have seen in 7 years of commuting. Oh, and I can plug my laptop in now and sometimes I even get power.
Somebody once told me that they had seen a Sligo line timetable from 1906 and the running time for an express was within 5 minutes of the current value - I think it might have been 2 or 3 minutes quicker back then.
