37240 has been out of traffic for most of the year. It was running on a Howes V3.5. For some reason it suffered slow speed running in one direction . Full strip down at a friends found a rather prototypical 'no fault found'. Re assembly and re fit with Bifs V4.0 found the the problem still at large. Bogie swap then cured the issue . Fitted with a double dumbo Zimo speaker and a ESU powerpack under the bonnet has meant it now runs superbly. I wasn't happy with my original weathering so it had a make over as well .
