SW trains / Snow-covered building

Our first advent calendar window was a building - never seen that before. I wonder what else will be on this calendar?

In other news, as usual, when approaching Feltham on the train this evening, the guard announced: "For those travelling to Feltham, please move to the front seven carriages. For those travelling to Datchett, please move to the front eight carriages."

Then, unexpectedly, the guard added: "Be aware that the front of the train is where the driver sits to drive the train forward."

Needless to say, several of us sniggered.
