It starts on a snowy morning on the 07:27 Central Line train into town  

By the time we’re above ground again on the DLR it’s daylight.  

A day at the office doing important things. Stewart would like this office because you can see the aeroplanes (below you) but he would hate it because it’s 30 stories above ground rather than 30 stories below.

 
Finally the 18:22 departure to Paris. 

 Jorge intends to get a photo of the locomotive at Gare du Nord.
