Commuters face two more days of misery next month after unions promised to repeat the action which stopped almost all trains through Wandsworth yesterday.

The Associated Society of Locomotive Engineers and Firemen (Aslef) has announced plans to strike again next Friday and again the following Monday.

The news has angered commuters already seething at the unions' disruptive strikes earlier this year.

Property consultant Nicole Moon, 22, from Oakmead Road, Balham, said: "I think they are an absolute disgrace. I use the train to get to work in Richmond. They seem to strike over absolutely nothing."

Aslef is calling for all of its 900 drivers on South West Trains (SWT) to join the strikes. Aslef is angry that SWT used managers to cover for train drivers picketing during strike action earlier this summer. The strike in early summer started over a dispute about paying for cab fares for train drivers.

Putney, Queenstown Road, Wandsworth Town and Earlsfield - which are all exclusively run by SWT - will only have station staff present to warn-away passengers.

Although other train services will continue to run through Clapham Junction, SWT has warned commuters to stay away because of congestion.

Putney MP Justine Greening said: "I think it is unacceptable that commuters have to suffer. It is inexcusable."

SWT operations director James Burt said: "The unions are now asking us to promise never again to use driver managers to drive trains during a strike, something we can never agree to.

"I am sorry for the disruption this unnecessary action will cause you."

Aslef held a ballot of all its members in SWT which overwhelmingly supported the industrial action.

Keith Norman, the union's general secretary, said it was astonishing that since he had informed the company of the intention to strike, SWT had only approached the union at national level to make legal threats - and not to seek discussions aimed at reaching an agreement.

Mr Norman said: "I believe the company is using passengers to try to score points over the union. I am sorry the public will suffer rather than the appalling management."
