Calbourne
Appeal Launched

Estimates are coming in from various contractors for the repair of the O2 boiler. A preliminary survey was carried out with the competent person, (boiler inspector), listing the known problems and recommending a plan of action to make good the boiler for the next ten years or so.

Fundraiser Simon Futcher has launched an appeal towards the estimated £60,000 costs, and Iain McLean, who masterminded the HLF grant for the C&W Workshop is putting together an application for HLF funding for Calbourne.

Work has started in the removal of the old boiler tubes, but removal of the side tanks, cab and lagging is on hold pending fund raising decisions.

The list of proposed work on the boiler includes the following:

  • Firebox sides, renew 7 rows of stays.
  • Firebox door plate, renew all stays below firehole.
  • Firebox tube plate, renew lower half,
  • Firebox crown stay bolts, renew.
  • Foundation rivets renew.
  • Smokebox, renew.
  • Smokebox tubeplate rivets renew 30.

Further work may be revealed once the lagging has been removed and the firebox plates have been cut out.

Consideration is also being given to renewing the side tanks. The bunker will be extended using the original Macleod back plate and side extension pieces fabricated during the rebuild of 1992.

Down Under
4149 in 'sorry state'

The underframe of bogie coach 4149 has been found to have excessive corrosion at critical parts of the structure. A detailed survey of one end was recently carried out with the bogie removed. It revealed weaknesses in the main longitudinals that can't be ignored, so the vehicle remains out of service pending repairs.

Back on track?s

A detailed survey of all the passenger stock underframes is being undertaken by Bob Millard, with a view to starting a refurbishment programme, to ensure the future serviceability of our historic vehicles. A review of the facilities available to do the necessary underframe work all year round has identified the need for an additional pit, long enough to work on bogie vehicles. The proposed location of the pit is on the wheel-drop road adjacent to the new C&W workshop. Currently the standard examinations which take up to three months to complete, are carried out in the winter / spring, on the down sidings, effectively halting all locomotive work and causing endless hours of shunting.

Helping hand?

The new full-time position for a C&W underframe Chargehand fitter, identified last year, has be filled by Rick Corbin, who has been involved with the railway for many years as a volunteer and contractor. We wish him the best of luck!

April 2004

What happened to January, February, & March?
No Mechanical Times since December

It was a case of either catch up on an already slow and frustrating start to the winter programme or carry on as normal and accept the consequences of having nothing to run the trains with in 2004. To produce an edition of this newsletter takes only a couple of hours, and is required to keep everyone from the latest new recruit to the Company Chairman informed about the latest developments in the Mechanical Engineering Department, but those were hours we simply couldn't afford. The now separate Carriage and Wagon Department was unable to attract a suitable full time fitter and the annual examinations of all the serviceable passenger coaches has fallen to us to complete again. A pressing need to complete the re-tube on Freshwater and an over-due valves and pistons examination for Royal Engineer left little time for non-essentials.

Coach Exams Expose Hidden Problems
Four vehicles withdrawn

Two bogie coaches, 2416 and 4149 were stopped pending further investigation on the 'A' exams this year. Concerns were raised about the integrity of the main frames. A lift off the bogie for one end of 2416, and plenty of cleaning off and re-painting has since revealed the extent of the problem. Localised corrosion and a bent headstock are the main concerns, and provision has been made for monitoring the defects whilst the vehicle is returned to service for this season. The other bogie brake, 4149, has yet to be investigated.

The two latest four-wheelers, 2343 and 2515 have been found to have defective brake cylinders. 'Wrong side' air leaks showed up the problems, which were caused by badly pitted internal walls of the cylinders. Replacements have been purchased and will be fitted as soon as possible, allowing one of the vehicles to form part of the forthcoming Royal train.

Royal Engineer
VP exam over runs

The valves and pistons examination of 198 was commenced directly after the New Year, and identified the need for new slide valves. Phosphor bronze valves replaced the worn out cast iron ones. The ports were trued up and new metallic packing was fitted to piston and spindle glands. The slide bars were adjusted to compensate for wear on the crossheads.

Although this work took longer than expected, the engine was ready for a bit of running in on ballast trains before taking the first passenger trains of the season. The characteristic squealing of new valves has almost disappeared now, as has most of the rattling from the motion.

Ajax
Looks like it's nearly finished?

One day's break from underframe work in March meant a fitting of five items onto the ever-progressing locomotive. It's surprising what difference two tanks, two sandboxes and a cab makes to an engine. Now Harry has something to get his teeth into on the painting front.

The livery chosen for Ajax is black with red bands and white lines, in the style of the Isle of Wight Central Railway.
