Thousands of people are due to descend on Sheffield's Hillsborough Park today for the start of this year's Tramlines Festival.
And many will be affected by a tram strike by the union Unite in a row over pay. Replacement buses have been put on by Stagecoach Supetram who say they are 'extremely disappointed' with the decision to strike during the three-day festival.
It's the latest and longest strike by Unite, who have branded the latest pay offer 'insulting'.
Stagecoach said it would provide a replacement bus service between 7am and 7pm on all three days, with a limited number of trams running within the same period. A full timetable can be seen here

It's the first time in the festival's 10 year history that it has been held outside the city centre.
