The Polar Express
 

Just noticed the IE 'Wishing our Customers a Happy Christmas' poster on platform 7 in Heuston this morning.
3 trains, including a commuter one and the MK4 merrily speeding along through the snowiest scenes ever (drawings I think and the 3rd train might have been the Enterprise but the memory's not what it was)
edit The third train is a DART.

Cynical being that I am:
I distinctly remember standing on the platform a few times during the first year I moved down to Portarlington waiting for very very delayed trains because of the snow :D
It's the thought that counts though.

IE corporate communications irony.:D

They'll be first in line to blame the snow. Well spotted.
