An example of the quality of the work we are doing can be send by these two cubicle boards as a before and after look at the Compressor Contactors CC1-CC4

21st December 2003

Work has continued on painting & varnishing the cubicle frame. Although the wiring in the frame in generally in excellent condition and of the newer grey type we have found that the wiring to the fault resistors (on top of the cubicle) has been heat damaged resulting in brittle insulation. We have therefore today, 21st Dec 2003, removed the looms of wiring relating to the fault resistors for replacement with new wiring. The work will be undertaken over the coming weeks.

The outside of the cubicle will be finished in Rail Grey gloss, however the inside of the cubicle is being coated with new anti-tracking white varnish.

A rare chance to see the top of the control cubicle which is not visible once installed in the loco. This is all resistor banks with the 3 large "curly" ones in the centre being the Field Divert ones (Z1,Z2,Z3).

Some sections of the cubicle are now complete as can be seen from these pictures:

    M6, M5, M4 - Motor Contactors

    M3, M2, K, M1, HC1, HC2 - Contactors and reverser. Some new wiring as old contactors had been "cut out" whilst at Booths.

    S1, S2 - Start Contractors. All new wiring as old contactors had been "cut out" whilst at Booths.

    CU5 (Rad Fan Control Unit), CU12 (Lighting Timing), EAC, and PC relay.

    AEI box is now back on top of the cubicle and refurbished door refitted.
