Brief Outline Key Facts History

Brief Outline

Built by English Electric in 1962 and withdrawn by BR as 37 032 in 1993, it also carried the number 37 353. It was first allocated to Hull Dairycoates. It was unofficially named "Mirage" at Tinsley in 1992. It arrived at Sheringham in September 1994 and made its first movement on NNR under it's own power in August 1996. Its first passenger service on NNR was on 31 August 1996. It then ran until last year when it was withdrawn for overhaul. It is intended to restore it to as is reasonably possible to its original condition.

Diary  
April 2007 D6732 is undergoing Classified Overhaul at Weybourne
To this end much work has, at April 2007, been completed:-
1. Bodywork re-skinning 80% complete.
2. Cooler Group compartment and Radiator Shutters cleaned and repainted.
3. Repairs to corroded electrical conduit and fire protection pipe work carried out.
4. 7 bogie brake cylinders replaced with overhauled units, 3 left to do.
5. Pipe work below Solebar level cleaned and painted.
6. Burnt out lighting wiring renewed.
7. New bodywork given ‘temporary’ coat of green paint for protection until the loco is ready for final painting.
8. Battery box cleaned and repainted.
9. Buffers removed, sent away to Oleo for overhaul and now returned for re-fitting
10. Fire Bottles currently removed for weighing and recharging as necessary.
11. New window rubber seals procured. No.1 end glass will be reinstalled.

Once the bodywork repairs are completed and all cutting, grinding and welding has finished, then the Exam work will start in earnest. Bogies will be steam cleaned/jet washed so that springs, suspension and brake rigging can be examined, lubricated and adjusted. Bogies will then be painted.
Traction Motors will be examined for brush wear and general condition with gear case and cannon box lubrication carried out. Motor suspension and cooling systems will all be examined and repaired as necessary.
Above the solbar all systems on the locomotive will be examined for general condition and wear with repairs carried out as necessary. This includes items such as Exhausters, Compressors, Traction Motor Blowers, Fuel, Lubricating Oil and Coolant pumps. All Electrical systems will also be checked for wear and operation of relays, contactors, safety interlocks etc.
Air systems will be tested and valves checked for correct operation, cleaned lubricated and repaired as necessary.
The power unit will receive new air, oil and fuel filters along with an overhauled set of injectors. The engine, turbochargers and intercoolers will then be cleaned checked and adjusted in accordance with specifications.
A new set of batteries will almost certainly be required after which the locomotive will be able to be started to allow full functional testing of systems and calibration of gauges. After the engine has been proved to be running satisfactorily, a full lubricating oil change will be carried out.
Once all this is completed in line with the exam schedule, the locomotive will undergo light engine and loaded tests. Following any remedial work thrown up by these tests, it will then be ready for release to our painters who will paint it in an authentic livery as carried when the locomotive was brand new.
 
November 2007 Update

Work is proceeding at a steady pace. The majority of the bodywork repairs are now completed with just the No.1 end nose section and a few other areas still outstanding. In addition extensive repairs have been made to corroded pipework and electrical conduit, also the Radiator Compartment has been cleaned and painted with equipment repaired as necessary.
Attention is now moving onto other areas of the locomotive. Earlier this year the buffers were removed and sent back to the manufacturer (Oleo) for refurbishment. These have now returned and been refitted.
Bogie brake cylinders have been removed and refurbished. The final three refurbished cylinders are on hand but remain to be fitted in due course.
The No.2 nose end has been stripped out and necessary repairs have been made. It is currently being thoroughly cleaned before being repainted. In addition all the machinery which is normally found in this compartment (Two Vacuum Exhausters, Traction Motor Blower) has been removed, stripped down and cleaned along with two fire bottles which have been weighed. These machines are now being painted and reassembled ready for installation once the nose itself has been repainted.
Many of the valves associated with the braking system are also located at No.2 nose end. These have all been removed and are in the process of being cleaned, painted and repaired as necessary before refitting.
Once the bodywork has been completed, the electrical control cubical, engine compartment and No.1 nose will be similarly dealt with, after which attention will turn to bogies and traction motors which will be thoroughly cleaned, inspected and repaired as necessary along with all the brake rigging.
Once all repairs are completed, a new set of batteries will be procured and the locomotive will undergo thorough testing before painting into final livery. This will ensure that after release into traffic, the North Norfolk Railway will be able to enjoy the services of the machine for many years to come.
 

February 2008 The body overhaul is complete and the refurbished vacuum exhasters and blower have been replaced in the nose cubicle.
