I did very similar to you and bought in good big site in Wilkinstown and have now been commuting to Dublin on the Drogheda train for the last three years.
As the other poster said, the worst thing about Drogheda train station is getting parked after 7AM. There is absolutely no bother getting parked for the 6:59 service but after that it is a bit of a lottery. I would like to know how Mrs edenjohnny is going to do the journey in 1 hour 15 minutes when it takes 25 minutes just to get the train station from Wilklinstown? My routine is to leave the house at 6:25, catch the 6:59 train, arrive in Pearse at about 8:05 and then walk to Stephen's Green to arrive in work at about 8:15. That makes it one hour 50 minutes. The man benefit (and it is an outstanding one) of getting the train in Drogheda is a cast iron guarantee of getting a seat.
On the way home the trains are packed with not only workers but also school children and students. I always get the 16:15 out of Pearse and getting a seat on the train is in the lap of the Gods. Later trains get even busier so if Mrs. edenjohnny finishes work at, say, 17:00 then she is in for a daily nightmare. Once back in Drogheda you then have the traffic to negotiate. What is a plain sailing 25 minute journey in the morning can take anything from 30 minutes up to 50 minutes in the evening. It is my belief that the traffic lights in Drogheda are timed to create a jam and discourage motorway traffic from using the town as a toll booth bypass. At times it can take 10 minutes just to get out of the train station.
Saying all of that I love where I live and am, at the moment, still happy enough to continue this daily 4 hours of commuting. Sitting in the back garden on a Sunday afternoon listening to the silence and watching the swallows swoop is a joy.
