In November 2007 the whole tramway closed for the first time. It was closed for five months for the second part of an £11,800,000 upgrade. Blackpool Transport Services and Blackpool Council currently have a joint bid awaiting Government approval. It could give up to £77,000,000 for a total upgrade of the trams and tracks. In January 2007 the City Class 611 prototype "supertram" was being tested on the tramway. It caught fire as it approached Central Pier. This caused lots of damage. The driver managed to get out of the cab. The tram was built by Mersyside-based Tram Power. It was being tested as part of a bid to replace the current trams. The same tram had already derailed on 30 May 2006 at Starr Gate loop in trials then. A Rail Accident Investigation Board report said that the derailmet was because of wear and tear on the track. They said another factor was the new type of running gear on the two-car prototype.
