Of those, only 407 took part in the voting - 38 per cent per cent and well short of the proposed 50 per cent.
And only 287 of the 407 voted for strike action – 27 per cent and short of the proposed 40 per cent.
A Southern spokesman said: “We note that only one in four – 26.9 per cent – voted for strike action with more than half of RMT station staff members ignoring the ballot.
“While disappointed we urge the union to stop this dispute and save our passengers and staff further pain by becoming part of the solution rather than the problem.”
The union’s executive committee is currently deciding whether to order walkouts in its long running dispute with Govia Thameslink Railways (GTR,) Southern’s parent company.
Meanwhile the result of a ballot by more than 200 key Network Rail maintenance engineers belonging to the TSSA union was announced today.
It declared indefinite industrial action will begin from next Wednesday (24 Aug) meaning engineers will not take out of hours calls at night or at weekends.
But of the 220 balloted, only 60 bothered to vote – just 27 per cent.
There was not a single vote in support of full strike action while 51 supported “action short of a strike” – essentially a work to rule and withdrawal of any goodwill practices.
A Network Rail spokesman said: “With only 51 people out of a workforce of 36,000 taking action, and action short of a strike at that, we are pretty sure there will be very little impact indeed.”
