What I do would like for the Rosslare line is clockface something that I can remember in pattern in both directions.
-A later train home from Connolly leaving at 19.30 to Rosslare serving Tara St,Pearse,Dun Laoghaire even Kilcoole then going as fast as the tracks will glide the train to the following stations until it reaches Rosslare.
-New trains, IE for example putting a 4coach 29k on the new proposed 13.30 find another 22k train
-Faster train times
-Try to give just that much top priority between Bray & Connolly
Do these simple things and you will have at least one passenger happy....
