There was more midwinter misery for travellers today with delays to mainline rail and Tube services.
An overhead wire problem at Dunbar in Scotland meant rush-hour di sruption for those travelling with the CrossCountry, East Coast and ScotRail train companies.
CrossCountry services travelling towards Edinburgh were terminating at Newcastle. A limited replacement bus service was operating between Newcastle and Edinburgh. An amended service was in operation between Edinburgh and Glasgow Central/Dundee/Aberdeen.
East Coast had a reduced service running from Edinburgh towards Newcastle, but with possible delays. No trains were running into Edinburgh and services from London terminated at either Newcastle or Berwick-upon-Tweed. A limited replacement bus service was operating between Newcastle and Edinburgh.
ScotRail services were replaced by a limited bus service between Edinburgh and Drem/North Berwick.
There were other difficulties for Scottish rail travellers due to o verhead wire problems between Kilpatrick and Dalmuir. This led to disruption to journeys between Helensburgh/Balloch and Glasgow Queen Street.
On the West Coast line, which was disrupted yesterday due to a problem at Wembley in north west London, there were further delays today due to a broken-down train at Bushey in Hertfordshire.
On London Underground, planned engineering work had already meant part-closures of the Jubilee, District and Circle lines, putting more pressure on other Tube services.
Passengers also had to contend with a part-closure of the Metropolitan line due to a signal fault at Neasden in north west London.
Tube travellers trying to switch to mainline services then found there were delays to Chiltern trains due to a signal problem at Aylesbury in Buckinghamshire.
The latest delays come as passengers prepare for fare rises on Friday.
Mainline season tickets will rise by up to 2.5%, while Tube fares will also go up by more than 2%.
There was travel chaos in north London at the weekend when overrunning engineering work led to the closure of King's Cross station.
This threw the spotlight on the salaries of Network Rail bosses and their performance-related bonus system.
Rail regulators are looking into the engineering overrun, which Transport Secretary Patrick McLoughlin has described as unacceptable.
Jubilee line general manager John Doyle said: " A signal failure at Neasden this morning caused delays on the Jubilee line north of Finchley Park and a suspension of the Metropolitan line south of Wembley Park.
"Our engineers fixed the problem as quickly as possible and services resumed at 8am. I apologise to our customers for any inconvenience caused."
