Tube train drivers unhappy with Transport for London have voted absolutely overwhelmingly for strikes on the Piccadilly Line.
The date(s) of the strike(s) have not yet been announced.
The Piccadilly Line is the tube line which links the Heathrow Airport to the centre of London.
Advice - check before traveling. There won't be any strikes without announcing the dates and times first, at least a week in advance.
EDIT: now we know the dates of the first strike in July, coincidentally during the fine visit of that nice old man from overseas.
so here you go, boys and girls...
No tube trains on the Piccadilly Line from 9 pm on Wednesday the 11th all the way through just after midnight on Saturday the 14th, Bastille Day. Normally there would be a Piccadilly Line Night Tube on Saturday night but I wouldn't run down to the bookies to put money on that happening. Nor for everything to start smoothly on the day trains that day either. Because of the 21.00 start of the action on Wednesday evening I would expect everything to start grinding to a halt in the middle to end of the rush hour on Wednesday.
