Greystones is correct!
I had a beast of a time for an hour or so there. I'd ridden up from Wicklow behind a pair of 121s headed by 132 and bailed at Greystones. A few minutes later 149 (in the picture) rolled into the down platform on an short engineers' train and ran round. 001 class no 025 then came north with an ammonia train from Shelton Abbey, and another few minutes later another 121 class rolled in at the rear of the 3 car Bray > Greystones push pull shuttle formed of ancient AEC DMU stock with the engines removed. 149 pulled off back towards Dublin and the push pull followed it with me on board when it had cleared the section at Bray.
