Engineering Report - Adrian Corke


Most of the closed season we have concentrated on many of the niggling jobs on the locomotives that could not be tackled whilst they were needed to operate the train services.

Metropolitan No. 1

Following the discovery of holes in the water tank in the coal bunker, Bob Randall has spent an amazing amount of time grinding and preparing the sections of the tank that are serviceable, ready for the new plate to be welded in place.

The steam brake has been refurbished and is now in excellent condition; a new lubricator for the steam brake has been fitted which should cure the problems with a lack of lubrication, something that we discovered when the brake was dismantled.

By the time you read this the replacement ash pan will have been fitted; however to keep costs down all of the damper doors and linkages will be recovered from the old pan and fitted to the new unit.

Both injectors have been overhauled, which also includes steam valves of the correct length, which should make the injectors easier to use, as we will be able to fit the handles permanently.


Coventry No. 1

Both injectors have been overhauled, the problem with the driver's side injector has been traced to a crack along the side of the clack valve, causing steam to leak past and overheat the injector.

Coventry had its first outing of the year to the North Norfolk Railway, and the feedback from the NNR is that they were very impressed with its performance and may well want to hire her again.


7715

A deal has been reached between Quainton and Barry Gambles of South Coast Steam Ltd to repair the boiler of 7715 and carry out some other work as necessary in order to return 7715 to steam at the earliest opportunity at no cost to the Society. In return for this the Pannier will be loaned to South Coast Steam for the next five years, they will be able to hire the locomotive to other railways agreed by both parties. 7715 will return to Quainton once a year for a couple of weeks at a time.

The locomotive will return to Quainton in 2011 with five years left on its boiler certificate, which will coincide with the 10-year boiler inspection of Metropolitan No. l.

It was becoming obvious that we will not be able to afford to repair 7715 in the foreseeable future, and that there are other areas at Quainton that require investment to improve the experience for our visitors. This is the most cost effective way of returning 7715 to steam in a reasonable time frame.


Millom

Much time has been spent machining all of the components for Millom through the summer, to ensure that we could fit the wheel sets and motion with barely any delays.

The locomotive is now a full rolling chassis and by the time you read this will have the outside motion and brake gear in place. The opportunity was taken to run the chassis up and down the demonstration line to make sure everything was in order, before any more components were added.

The boiler has passed both its hydraulic and out of frames steam test and is ready to be fitted to the frames. The boiler will be fitted during the next crane day, hopefully before the start of next season. (Stop press - the boiler was reunited with the frames on Saturday 31st March).

Beattie

The locomotive has been test steamed on its return to Quainton, and by the time you read this will have returned from the Mid Hants Railway, after appearing in their gala in early March.


Churchill Coach

The coach is to receive a fast track overhaul. At this stage the successful contractor has not been identified. But, again by the time you read this the coach may well have left Quainton for overhaul


No. 66

Hunslet Austerity No 3890 (No 66) is the last steam locomotive built for commercial use in Britain.

The locomotive has now been dismantled ready for dispatch to the contractor. The plan is that the locomotive will have all of the work carried out that we cannot do on site at Quainton, and will return to us for final assembly and finishing work to be carried out.

The reasoning behind this move is that both the wheel sets and boiler require attention, and that removing the boiler at Quainton will simply add costs that we can avoid, and spend that money on other work on the locomotive.
