Some train services across London will be cancelled today after a week of disruption on the capital’s railways.

ASLEF union has carried out an overtime ban for train drivers this week, with the action culminating today (October 6).

It comes after a full strike by the union on Saturday (September 30) and Wednesday (October 4).

The disruption today could impact mainline train services across London, with some rail operators already implementing a reduced timetable.

These include c2c, Chiltern Railways, Gatwick Express, Great Northern, Southern and Thameslink services.

Operator c2c, which runs some main line trains in Essex and east London, has announced a reduced peak time service, with two trains per hour off peak on all routes.

Chiltern Railways, which operates trains from Marylebone, said that it would run a “reduced service”, and that there would be changes to early morning and late night services.

Its trains will not stop at Lapworth, South Ruislip, Northolt Park, Sudbury Hill Harrow and Sudbury & Harrow Road, Harrow-on-the-Hill, Rickmansworth, Chorleywood, Chalfont and Latimer, or Amersham today.

Govia Thameslink railway – which runs Gatwick Express, Great Northern, Southern and Thameslink services – has said that an amended timetable with fewer services will be in operation.

It warned that services will be busier than usual, especially in peak hours and that passengers should allow extra time for your journey.

There will be no Great Northern service at Moorgate, Old Street, Essex Road, Highbury and Islington, and Drayton Park.

Other rail operators have said that the overtime ban makes it likely that some short-notice alterations or cancellations to services will take place.
