London rail disruption on first morning commute of 2022
It was partly caused by the number of workers self-isolating with Covid-19
Rail passengers have been hit by disruption on the first working day of the year in England and Wales due to a combination of faults and coronavirus-related staff shortages.
No London Overground services were able to run between Clapham Junction and Surrey Quays on Tuesday morning due to a fault on a train.
National Rail Enquiries warned passengers that a "problem under investigation" between Darlington and York was causing disruption between the stations.
This affected CrossCountry, London North Eastern Railway and TransPennine Express services.
Urgent repairs were being carried out to replace part of the signalling system in Slade Green, south-east London, following an electrical fault.
The issue meant the line through the station towards Dartford was blocked, affecting Southeastern trains.
Network Rail tweeted that it sent technicians to Lewisham, also in south-east London, to fix a new set of points which "worked fine all night in testing and of course has gone wrong now".
The problem caused disruption to Southeastern services on one of the main lines into the capital.
Rail journeys across Britain were also being hit by many operators using reduced timetables in a bid to improve reliability after weeks of short-notice cancellations due to staff shortages caused by the coronavirus pandemic.
Southern is not serving London Victoria until January 10 and CrossCountry has removed around 50 daily trains from its timetables until next week.
Demand for rail travel is at around 50% of pre-pandemic levels.
This is partly due to the guidance for people to work from home.
