I can't see that this will cause the project to fail, afterall, similar things have happened to a lot of other vehicles (look at the Citaro bendy buses in London), which have been sucessful. The main difference is that with other types, the faults have occured once the vehicles were in service, wheras at least this happened during testing, so modifications can be made before it enters passenger service. If it does fail due to this, it suggests that it's best to rush a design into production, and wait for faults to occur when in passenger service, and hope they don't kill or injure anyone, since by that point it's to late to go with another design. Overall, this seems like a very good design, especially if it's low cost allows places to go for trams that would otherwise find them too expensive, and if it saves the Blackpool system. The fact that it's British is nice too.
