Yes... I should have said heading east rather than north really shouldn't I?!
If it helps... looking at Real Time Trains the closest match on the timing is this one; Stratford Country End Junction at 18.44:
Realtime Trains is an independent source of live realtime running information for the Great British railway network.

If I have traced the diagram properly, it has ended up at Clacton on this one:
Realtime Trains is an independent source of live realtime running information for the Great British railway network.
www.realtimetrains.co.uk
...which suggests you'll need to check anything that starts at Clacton tomorrow morning.
You should probably post a request for it ( and the other one ) in the Urgent thread.
