NEWS> July 13, just announced - drivers voted overwhelmingly for further strike action, company given £13M fine
UPDATE
NEWS> July 18, Southern Drivers will be striking August 1st, 2nd, and 4th. Expect major disruption on Southern and Gatwick Express. Also, Virgin West Coast Drivers are on a "Work-to-Rule" which means no overtime or flexibility. And Southwest Trains out of Waterloo are balloting for strike action regarding the same removal of Guards from safety critical duties.
The summer isn't half over yet. Times are difficult.
FLASH July 20 The strikes on Southern and Gatwick Express by both Drivers and Guards which would have brought the system to a halt on the 1,2, and 4 August have been suspended as the Government has called for urgent talks between it and the two unions, ASLEF and RMT. If talks go well perhaps there can be a resolution to the very long strike season which has caused untold misery to commuters and tourists, as well as the affected members of staff. Let's hope so.
So, at the moment, nearly normal service on Southern - aside from lines where staff have been pulled back by the company - and a normal service on Gatwick Express.
