I'm surprised you didn't hear it! Nice chugging noise to it. My dads a big railway fan so he was happy to get to see it, but I think he would rather have been on board it.
Unfortunately I didn't get down to Dublin today, although I went to both BFS and BHD so got a nice collection of photos. Cloudy weather though so their quality is limited. Cloudy weather will not prevent me from photographing aircraft!
