The BR TIMES website shows the minimum connection times as being:-
Stratford (London)...........7 minutes
Stratford International......5 minutes
It was Wickford I was referring to - to justify the 3 minute connection
We make our way to Cricklewood station to catch the 1005 Thameslink train towards Sutton, going all the way to Sutton, where we arrive at 1206 on Monday afternoon (just about!)
I really don't understand what the obsession is with the south coast?
