No they are not but when a main line is closed all weekend you would expect better co-opration between two companies operating the one line still open.
I point out again for the umpteenth time there was still a service, not a train but a service was still in place... :roll:
There are lots of lines i see grassed over at Crown Point they could open them up for spare capacity or open up the line next to platform 6 at Norwich that seems to be empty most times i am there.
In the last three years I've seen nothing sat on those lines and would presume a fair amount of money would be needed just to get them into a state to sit stock on. The sidings behind 6 (hitherto the Jubilee) are all in regular use. At 0400 there will be maybe 5 or 6 AGA units in there, 2 or 3 EMT units. During the day there is often a few units in there, tampers sit in there as does the short hauled set. Same goes for the sidings the other side of the station, they can have all sorts in there, full IC sets, the short set, various DRS locos and a few of the sidings are used by DBS for shunting stone trains. Even the middle road at Norwich (between 4 & 5) can be playing host to units or now and again a 90. Just because there is nothing there on a Saturday afternoon doesn't mean its unused.
And anyway, its all academic. These spare units don't exist and even if a spare unit was at Norwich the 14.12 would still have been cancelled and not replaced by said spare unit given it would eventually arrive at Cambridge long after the 15.12 would have left!
