007 Licenced to kill leaf mulch !
Post privatisation but still in Network SouthEast livery Railtrack Plc owned Sandite/De-Icing unit 930 007 is seen waiting at Hastings to form sandite train 8Z42 13.20 to Tonbridge.
This departmental unit was one of the batch authorised for conversion at Selhurst Depot between 1977-82 from redundant 4-SUB (class 405) motor coaches. Set 007 was formed of ADB975592 (ex S10993 from set 4127) and ADB 975593 (ex S12659 from set 4604). The no.1 end ADB 975592 was the De-icing vehicle fitted with polythene lined steel tanks to prevent the tanks becoming live when de-icing fluid was being released onto the conductor rail. The no.2 coach ADB 975593 was initially empty on conversion but subsequently modified and fitted with hopper vats to carry Laponite solution (commonly known as Sandite). When laying sandite the train would be restricted to 20mph hence the class 8 headcode where as de-icer could be laid at 45mph. The units were fitted with extra shoe gear to create better contact in icy conditions and two shoes, one either side were fitted with air operated vibrating pins to dislodge any formed ice on the conductor rail rather than just frost or snow. Formed ice blobs could be a problem under overhanging structures like bridges where water could drip and freeze creating a lump on the conductor rail.
