FIRST Capital Connect appears to be one of the worst railway victims of the weather, after a skeleton service was introduced last night. The company warned its customers that last trains might not run, and that services today would also be very limited.

FCC services between London and Brighton were withdrawn by early afternoon yesterday, and at least 20 units were reported to have become becalmed in sidings at Cricklewood. Replacement buses were running between St Albans and Hitchin, and also between Luton and Bedford.

Door faults caused by impacted snow were said to be one factor, and FCC is also struggling with the effects of what amounts to a work to rule by drivers, who have in many cases been declining to work rest days and overtime since early November because of a pay dispute.

The prospects on FCC do not look very bright today, either, after another bitterly cold night in which temperatures north of London fell towards minus 10 C.

No FCC services are expected on the Wimbledon/Sutton loop, and even the core Thameslink route between Bedford and London is likely to have only a limited stopping service.

Other operators are also facing more problems this morning. East Coast services (pictured) between London and Leeds are still reduced, and there were warnings that many EC trains could be delayed by emergency speed restrictions. Southern expects to cancel a number of trains again today, mainly in the off-peak, while although South West Trains is hoping to run a full service it is still warning of possible delays.

National Express East Anglia will be cutting its main London-Norwich service to hourly again today, and the frequency of Stansted Express has also been reduced for the second day running.

There will be no Transpennine Express services from Manchester Airport to either Newcastle or Glasgow today or tomorrow (Saturday).

Full services are expected today on most First Great Western intercity routes, although one train between Cardiff and London will cancelled each hour. There are special timetables on a number of FGW suburban lines, including those to Bedwyn and Marlow, and no trains will be running between Swindon and Westbury, again for the second day running.

CrossCountry is being disrupted again by yesterday's rockfall in Wickwar Tunnel, between Bristol and Gloucester, and also by a freight train derailment at nearby Yate. As a result, trains from Manchester to Bristol are being terminated at Birmingham New Street, while trains from Plymouth to Newcastle will again be diverted via Chepstow, adding some 90min to their journey.

Eurostar services remain limited after yesterday's train breakdown in the Channel Tunnel, with early morning and evening cancellations expected to continue until Sunday.

Network Rail staff have been out in force again overnight, running de-icing trains and clearing points. A further update on running conditions nationwide will appear on this site shortly.
