Minor thing but why is it that sometimes when you catch a train out of Heuston do carriages recently unhooked from the locomotive that brought it in get shunted up a good 50-100 metres more than what I would have thought necessary? Occasionally as well you can be sitting on a train (normally with say 15-20 mins still before departure) and they will move the train up a short distance further away again. It is a very small point but bugs me sometimes especially if you are walking to platform 1 or 6,7,8 where you have enough walking to do as it is.
I am sure there is an obvious reason and it only happens say once every 15-20 journeys but I would still like to know why. Has anyone else ever noticed this?
