Parts of the railway line in Kent will be closed until Wednesday afternoon due to continuing staff problems caused by strikes.
Members of the rail, maritime and transport union are due to walk out on Tuesday June 21, Thursday June 23 and Saturday June 25 over wages and working conditions.
However, strikes will still impact rail services on non-strike days.
Although many stations affected are smaller and more rural, such as Martin Mill near Deal, some larger stations such as Ramsgate and Canterbury East and West, which are on the high-speed route to London Victoria, will also be affected.
A Network Rail spokesman said: ‘The area is supplied with electricity by a local electricity control office which we know will have unique staffing issues on Wednesday, due to the railway strike.
“Safety checks on the power supply to trains – called continuity tests – will have to be carried out first thing in the morning.
“It’s about making sure all the power supplies are working properly before the trains run. Failure to perform these checks could result in trains stopping without power on a hot day, which would be an unacceptable risk.
“We are working with Southeastern to reintroduce line-by-line trains, working around East Kent.
“It will take around seven hours and we urge passengers to check before traveling on the day.
“We are very sorry for this additional complication and we must point out that some lines will not have trains on Wednesday until well into the afternoon. Please check before traveling on the day.
Here are the railway lines and stations concerned:
– The Sheerness Line affecting all stations between Newington and Sheerness-on-Sea
– The Medway line affecting all stations between Newington and Faversham
– All stations between Westenhanger and Ramsgate
– All stations between Faversham and Ramsgate
