DRIVERS at troubled train privateer Southern cut their strike action down to three days next week, their union said yesterday, while warning that disputes over driver-only operation could spread to other routes.

Aslef announced that the walkout, which was due to run for six days from next Monday, will now only take place on Tuesday, Wednesday and next Friday.

Aslef members will strike again on January 24, 25 and 27, when all services will be cancelled.
