This picture shows the traction motor contactors 6 and 5 (l-r) and the main earthing and neutral terminal bars. Three of the six traction motor contactors have auxiliary contacts fitted to them (M4, 5 and 6) for control wiring. As the three motor contactors we obtained for these positions were all missing their auxiliary contacts and paxolin actuating arms, an arm was removed from a spare motor contactor, fitted to an overhauled auxiliary contact block, which was fitted to M6 and tested. 6 January 2008.
