This is a bit like when the ECML was closed. NXEC ran buses, but Hull Trains diverted, and were the only company running direct trains between Kings Cross and Doncaster. Everybody avoided the rail replacement buses and crammed onto Hull Trains services, resulting in terrible overcrowding. The same could happen on 8th/9th November - from what I can see, Hull Trains are again diverting, but NXEC are only diverting Scottish services, none of which will be calling at Doncaster.
Some information that may shed some light on this matter:
NXEC are diverting services between Peterborough and York on Saturday 8th and Sunday 9th November. Not sure which route, but believed to be via Spalding, Sleaford, Lincoln, Gainsborough and Doncaster to York.
More info.......
Yes indeed, the NXEC diversions are definitely via Peterborough, Werrington Jn, Spalding, Sleaford, Lincoln, Gainsborough Lea Road, Bessacar Jn, Doncaster. The up trains may use the Sleaford avoiding line, the down trains may not because the down avoider is completely overgrown! Trains will be worked by NXEC crews who are learning / refreshing the route at the moment using a combination of service trains and NXEC class 67 thunderbirds. Believe the possession is for relaying the up line through Peascliffe tunnel.
The timetable for 8th and 9th November is not bad at all. On the Sunday there are hourly HSTs between York and KX but note the lack of Doncaster calls, this combined with set down and pick up restrictions at Peterborough prevents Leeds passengers from benefitting, they will be funnelled via the Newark-Grantham bus. But then trying to cram all passengers from Leeds, the North East and Scotland into one train an hour would not be a wise move.
