A politician has called Govia Thameslink Railway (GTR) chief executive’s resignation “nothing but symbolic”.

Charles Horton announced his resignation from the transport company last week, following uproar over delays and cancellations of services since a new time table was launched last month.

The Thameslink line serves commuters in St Albans, Harpenden, Radlett, Borehamwood and parts of Barnet.

In response to his resignation the London Assembly spokesperson for transport, Florence Eshalomi said: “To Londoners whose lives have been disrupted by the drawn-out chaos caused by GTRs comprehensive failings, this resignation will be little more than symbolic.

“I urge the new chief executive to immediately get to grips with improving the franchise’s service across the board and putting an end to the continual delays and cancellations.”

The company said Mr Horton will remain in post for a short period to oversee the development of a temporary timetable to address the recent major disruption to rail services.
