I am EXPECTING that the unidentified unit I saw above (post 291) coupled to 377606 is 377609. I might get the 1806 departure off London Bridge to West Croydon as I was hoping to confirm that. BUT if its on an East Grinstead or something then I am going to wish I took my usual route Victoria to East Croydon !. Still a fly past of Selhurst Depot from Norwood does not hurt - IF I am quicker this time !.
I am only aware of the one in-service diagram so far :-
06:32 Norwood Jct to London Br
08:02 Norwood Jct to London Br
17:05 London Bridge to West Croydon.
18:06 London Bridge to West Croydon.
And that the evening pair of runs are more reliable than the morning.
Is the above the first or second diagram for 377/6s so far. I assume East Grinstead is more likely to be third diagram. Or have I misread the thread in the past ?.
That is the first set of diagrams that they were already working.
The other 10 coach diagrams for 2 x 377/3 + 4-377 are (according to the diagrams on ukmodernemu)
0702 Norwood Jct to London Br
0832 Norwood Jct to London Br
0936 Crystal Pal to London Br
1636 London Br to West Croydon
1712 West Croydon to London Br
1736 London Br to West Croydon
1812 West Croydon to London Br
1836 London Br to West Croydon
This works out and back from Selhurst (312/311/188)
and, from Streatham Hill (198/314/315)
0624 Victoria to E Grinstead
0736 E Grinstead to Victoria
0853 Victoria to E Grinstead
1507 E Grinstead to Victoria
1623 Victoria to E Grinstead
1737 E Grinstead to Victoria
1853 Victoria to E Grinstead
2007 E Grinstead to Victoria
but this one involves some splitting of the four coach at the middle and end of the day.
Please note that this is only based on the information in the old diagrams and I could clearly be wrong.
By getting 377/6s on these, 6 377/3s and 3 4-coach 377s are made spare. Presumably the 377/3s become available to replace 6-coach 455+456 formations and this releases 456s to store.
