LONDON - The British Union Maritime and Transport Workers called for the country's Transport Secretary Chris Grayling to step down on Friday, after days of Northern train chaos since a new timetable was adopted.

The union's general secretary Mick Cash told media that his members are facing public anger "without a shred of support" from Grayling or Northern's management.

The move came as the railway company had canceled over 200 services with other services being affected.

This constituted part of passengers' frustration as they have to face widespread cancellations and delays since a timetable change was adopted on May 20.

Grayling has not responded to the resign call.

Greater Manchester Mayor Andy Burnham told the BBC he understands Northern will introduce an emergency timetable.

A spokesman for Northern said there will be "amended services" from Monday.

Since May 18, more than 2,000 Northern services have been aborted.
