Progress on London Suburban tank (N7) locomotive

 

London Suburban tank (N7) locomotive progress:   Nov2020

 

The forthcoming winter months will be a testing time for the loco team as they prepare the boiler for expert examination. Boilers in regular service in the days of steam, were not expected to last long periods. In preservation heat stresses imposed are greater, as they have longer periods between firings, resulting in thermal cycles between longer cold periods of stagnation to short in-service temperatures.

 Both external, and more importantly, internal surfaces have to be prepared this is generally done by needle gunning. Surfaces then descaled so just bare metal is exposed. All the superheater elements and boiler tubes have been extracted, these are considered consumable items. Other parts removed are been labelled and placed into storage.

During the tube removal works significant quantities of internal scale were found around the exterior of boiler tubes which would have significantly reduced efficiency, leading to poor steaming. It is most important that water treatment is applied to reduce scaling, if and when the boiler can be steamed again, attention to maintenance routines is essential to prolong the life of the boiler. In retrospect hire periods away from home, not supervised, have not aided the locomotive’s condition.

Much of the inner firebox is inaccessible and is difficult to inspect. Within preservation groups there is some controversary on the best way to manage difficult decisions between maintenance and replacement of boilers. To try and help resolve these a number of Non-Destructive tests are in the process of further development.

To give an appreciation of the difficulties of boiler maintenance, faults can be found in many places. A non-exhaustive list includes, fracture or cracking of stays, cracks between stays, grooving near the foundation plate, internal corrosion in a firebox. Normally these are regularly checked working to a schedule of examination.

Once a boiler is lifted out of its locomotive frames, a stricter regime applies for inspection. Only when fully accessible can metal surfaces be fully tested, most critical is the strength of firebox, requiring the services of a boiler inspector. Without such investigation and expert opinion works any boiler would be uninsurable and so could not be used.

These investigative works are led by Michael Sanders assisted by his locomotive team, those include Matthew Cornell, Joshua Fortescue, James Jaeger, Dan Stevens, Adam Baines and Eddie and others whose contribution has not been communicated to your reporter.

Running shed progress

 Rapid progress in building the Running shed

It is a test of resolve that during the difficult times, volunteers who are physically able, have been progressing museum development with some very visible results. This acceleration of works was possible with a cessation of the first Covid lockdown, and better weather conditions. 

Within a few weeks an empty shell without track, is replaced by a Running Shed shelter. This rather bare open outlook shed photo was taken end of September. 

Allan Robinson is (pictured below) demonstrating the manual concreting method that has saved several thousand pounds, by avoiding a commercial delivery of mixed concrete which would cost more need timber shuttering, and phasing purchase of materials.

Special thanks must go to Linda Robinson who was seen acting as Allan’s helper/ labourer / extremely understanding wife (* delete as appropriate), for the concrete mixing and laying duties that once completed got the whole ball rolling.

Installation of flat bottomed rail on 55 concrete sleepers followed, the gang here seen at work from the vantage of a railcrane. To do this work mechanical plant is essential, a large former military JCB was used for moving the sleepers, underground drainage and water diversions were made using the museum JCB. 

As a result, a rolling chassis of the N7 locomotive has been placed inside, and the DMU Power car stabled as seen outside, providing some weather protection. 

Hats off to all who contributed !.Allan Robinson and his helpers for concreting the foundations, the track gang installing rail. Currently the build activity is to install the first side panel and metal window.

Rebuild of Industrial loco Lamport No.3

An order for a new steel welded in a firebox is imminent, this is of course most costly part, it can be progressed as the rolling chassis has progressed well, through the work of the team notably Dick Allman, John Bicknell, Peter Merrick, Nick Proud and Allan Robinson. 

Currently only the handbrake is operative so a wooden pattern is been made by John Bicknell so brake blocks can be manufactured by a specialist engineering company in due course. Various welding jobs have been undertaken by Peter Suckling on a number of jobs in the shed, some noted below too.

The museum running fleet 

• Jubilee is the museums singular current runner, faults reported in the Drivers report sheets have been attended to by Joshua Fortescue and the loco team. An annual boiler exam is due in January 2021. 

• Number 11 has recently had some riveting work done and these will be awaiting a boiler inspection. 

• The loco team has started a proactive re tubing of number 54, as there's no known Thomas requirements for some while, this will ensure its longer-term availability. 

Diesel multiple unit trailer car DTCL  56358

Initially planned for a quick repaint, the carriage is now receiving a more thorough examination. If you remember this trailer carriage was in an advanced state of external shabbiness, the roof stripped back and repainted was reported by CN79 in March 2020. 

Since then Mark Cornell has removed windows and panels, which has highlighted the need for further maintenance. More extensive work can now make place in this “restricted season”. Apart from some internal changes, this is the most significant works since its arrival in 2003.

Peter Martin and Brian Sermons, flushed with success with the smaller W&M Railbus, have moved their tools kits to the larger proposition of the Class 101 unit. Slam doors are now receiving the most attention, wooden frames have become distorted, years of slamming and an external environment means that their wooden frameworks in some cases are reduced to some very flimsy structures. Wood splicing, filling and replacement is required even though the doors are metal skinned. A number of door thresholds have been made and installed. Body work repairs to fill holes and dents are required before any more thoughts of repainting. 

The tarpaulin (Hi Bar – B745522) wagon

After its rotten floor has been removed, body panels are strengthened and primed to stop further corrosion.  At least it is now stronger and in one piece. It is anticipated for completion within the next few weeks. In a better financial climate it would be fitted with a replacement floor, but tighter financial control dictates a more economical visual finish with a simple tarpaulin covering.

Museum Objects: Furlough tickets

 

Furlough tickets,  and complexity of ticket issue 

with rules and regulations

A word that has recently come back into our vocabulary, due to the Coronavirus pandemic. Originally this was a military term for soldiers, when they were not required to be on duty, and also not on leave, a state of “Furlough” existed. Involuntary furloughs because of economic conditions is a yet another which unfortunately the museum is familiar.  

In the ticket collection such tickets are see here issued for Military personnel. Wrentham and Brockham is a very sleepy village on the closed Thetford, Watton to Swaffham line in Nortfolk. Open scrub and heath in Brecklands, is an ideal military training area so Wrentham Camp established, and hence these ticket issues from that station, a smaller military camp is still there. Other ticket examples issued locally would be the issue of tickets from stations near various USAAF air bases to places of recuperation, like Cambridge and London, there may be some gems - but they will take some timely enquiries to find in the museum's large collection.  

The museum book archive also has a number of papers concerning the issue of tickets among many items of bureaucracy which on first thoughts you might think was the last thing on peoples minds in wartime. However evidence suggest that rules and regulations were very much to therefore, and like the current Covid pandemic created complexity, 

One such example is reproduced here - as it shows the complexity of booking railway tickets – even in the time of War. The “BOYS” section for example uses the word “Furlough”, the idea of “boys” in the service of the nation in wartime – does belong for the history books.

Did a booking clerk have to question people's motives for travel ? - "Is your journey necessary" was a wartime expression, recently the idea of questioning a need for travel has re-emerged.

Railway carriage prints and the Birdcage coach

 

Donation of railway carriage prints. 

 

On Sunday 13 September Mr. John Leach a visitor that day, donated to the museum some framed railway carriage prints of Cuthbert Hamilton Ellis paintings. John had "liberated them" himself from withdrawn carriages to be broken up many years ago. Today these are considered of some value and have been recorded as accessioned items by Jaki Collison. 

What is striking is how diverse the railway scene was in earlier times. It is to be hoped that o at a future date displayed for the appreciation of a wider public. Railways were so much more varied in earlier times, something the museum can demonstrate today, no mono-culture of multiple units, steam locomotives of hundreds of designs and similarly coaches and wagons of every conceivable type

 

An example of one of the donated items, this pertinent to our area of interest:

 

Behind the locomotive is a "Birdcage" passenger brake coach, an example that the museum has restored in Platform 5. This was built in 1870, like the illustration’s noted date, and came from North Woolwich station museum that closed in July 2008 (SVS143 p12)

 

A second example, visually attractive because of its bright yellow colours, is a personal favourite reminding me of an attractive spot in the Peak District – Wetton Mill. There were others but they were packed away quickly and there is a need to see them again so they can be appreciated. Maybe some (suitably theft and UV protected) inserted into carriage print frames or displayed in a coach setting.
