Update from Saturday 15th November. By Ian Robins and Dave Hammond.

It was a busy weekend at Williton with many jobs being progressed on the locos as Ian writes.

Checks on the strength of antifreeze in the coolant of all applicable locos has been performed and the
concentration increased where necessary.

D7018 – Pipework has been painted ready for installation into the loco.

D1010 – Work continues in preparation for the ‘A’ engine change.  

D832 – John Cooke and Neil have fitted replica aluminium NBL works plates onto the bogies.  The original
plates would have been cast in brass but disappeared long ago.

D1661 – Routine maintenance continues.  This week I performed a main control cubicle examination checking
all relays and contactors etc. for condition and operation.  A broken spring was discovered on one of the
reverser solenoids requiring removal of the solenoid for repair.

Some slight arcing marks were noted on the reverser contacts which has got us thinking as interlocks should
prevent the reverser from being operated whilst carrying current. Finally, the cubicle was vacuum cleaned.
Last week I spent time carrying out a full cubicle examination.

D6566 – The bodywork overhaul has commenced in earnest at Cranmore, reports indicate some big holes
have already been cut in the sides!

D9518 – Behind the “Iron Curtain” Dave H continues to prepare the electrical cubicle and cab for removal from
the loco whilst components for the replacement Paxman engine were being worked on by Terry in the main

Dave details some of the work by the team progressed on Saturday:-

1) Transmission temperature gauge was removed to store:
Terry, assisted by  Dave, removed the Temperature sender from the Voith Transmission with attached
capillary tube through to the Gauge mounted on the Control cubicle. Tested, it showed temperature and was
stored serviceable.

2) Starter motor contactor box and cables LHS Engine Compartment Door 4:
The Starter motor contactor box and cables removed; the seized conduit that had held the box to the cab was
finally freed and put back serviceable.

3) Engine speed valve (ESV):
Ian tested the resistance of the removed ESV (Brush LH3 - Solenoid and Air Valve) and at plus 500 Ohms it is
in-line with the Brush assembly instructions for this type of Solenoid., it needs our usual cleaning and new
paint before sending to store.

4) Disconnection of wiring into the cab continued:
The cables (battery power) were disconnected and removed intact from the Plus and Minus terminals sides at
L/H and R/H lower of Control Cubicle and stored.
