BJ. c.c. to RG.{Mr Rowledge} E.{Mr Elliott - Chief Engineer} c.c. to DA.{Bernard Day - Chassis Design} HY.{Tom Haldenby - Plant Engineer} c.c. to Wor.{Arthur Wormald - General Works Manager} Expl. No. REF: Hed/T/64. 6. 25. EAC. 'V' SERIES. FABRIC COUPLING. X8305 The fabric coupling on 93-NK car has now completed 15,000 miles running in France, and is still in very good condition. We therefore think we can safely assume that under normal conditions, the average life of these couplings will be several years. It should however be expected that the couplings will be renewed when the cars are overhauled. They are not an expensive piece. Hs.{Lord Ernest Hives - Chair} | ||
