Two train stations crucial for access to a major music festival in Blackheath this weekend will be closed on Sunday.

OnBlackheath, now in its sixth year, brings internationally acclaimed acts and thousands of revellers to the area from July 13-14. 

Yesterday, SouthEastern revealed that the nearest two stations, Blackheath and Lewisham, will be closed for engineering works on the festival’s closing day, suggesting festival goers walk from Maze Hill instead.

On Twitter a spokesperson for SouthEastern said: “Are you going to the @ONBlackheath festival this weekend?

“On Sunday, Lewisham & Blackheath stations are closed for engineering work, so, please use Maze Hill station to get to the festival site.”

The announcement attracted accusations of poor planning, with one user commenting: “Typical @Se_Railway couldn’t organise one in a brewery. You total muppets close down nearest station to Blackheath festival.”

SouthEastern say that initial engineering work is planned over a year in advance, and cannot be rescheduled at short notice “as the tools equipment and teams will already be booked for elsewhere.”

The spokesperson said that the clash in dates was caused by a change in the fesitval’s dates, from September to July.

“The works were originally planned a long way out, on the basis the festival would be it's usual September date,” the spokesperson continued.

“When the date was changed, it was too late to change the engineering works plan, but we are already in discussions with the organisers for next year.”

Acts this year include headliners Jamiroquai and Grace Jones and support from the likes of James Morrison, Rag N Bone Man and Newton Faulkner.
