Vivarail have just published a full report on December’s fire at Kenilworth (pdf) during a test run of their class 230 DEMU. They identify the cause as a fuel leak, and note several design improvements that need to be made to avoid a repetition. The whole thing is an interesting read for anyone concerned with testing.
Having your train catch fire during what amounts to a full system test is a pretty serious failure by anyone’s standards, and it’s forced the abandonment of plans for a passenger trial this May. But despite the naysayers who seemed all too keen to dance on Vivarail’s grave, it’s a long way from terminating the project.
The concept of converting surplus trains from London Underground’s District Line into diesel trains by installing underfloor diesel generator sets to power the existing traction motors is a sound one. With running gear and motors dating from 2005 the trains have twenty years’ life left in them, and the conversions are far cheaper than new-build DMUs. There is some political resistance to “London’s hand-me-downs”, but something has got to replace the Pacers.
