Aw nice one Ciaran, I have been living alongside that line my whole life and I have never seen the Weed sprayer on that line, I presume it was its last visit when this was taken.
The run around loop and ground-frame was there until 2003/4, there pictures of it on Eiretrains eiretrains.com/Photo_Gallery/Railway%20Stations%20H/Howth/IrishRailwayStations.html
Excellent footage Ciarán, thanks for uploading. Is there mush of his old stuff left? I sure am glad Colm filmed all these things! Jesus 0:25 looks like someone's garden!!!:D There's a fair bit of spray flying onto the platforms at Sutton too! Two loco hauled trains in two days on the Howth branch must be a record:) Surely the Howth branch is sprayed every year along with every other line?
Plenty still to upload including my own! Yeah the Howth branch was sprayed every year like the rest but in the early 2000s they just stopped going to Howth, yet it runs on a brand new line to M3/Pace now.
I've more video from Donabate and other northern line places but they're on DV tape so it's not as quick to edit/upload. I think as the Howth branch is short enough it's done by track-gangs.
