Dynamic testing of Met 353 – November 2012

As recently restored 353 had not previously run in its current form (using a modified PMV underframe), it was necessary to bed in the suspension and brakes; and to build confidence in the performance and dynamic behaviour of the vehicle. The tests were undertaken on the Great Central Railway over a three day period, with mileage accumulation carried out on day 1 (Monday 19th November). For the initial test runs the carriage was sandwiched between two locomotives (Cl45 D123 and Cl20 D8098 ) to enable rapid reversals at the possession limits and build up mileage as quickly as possible.

Once safe operation at 25 mph had been demonstrated on the first day, the carriage was tested to 40 mph, then to a maximum higher speed of 50mph on day 2 (Tuesday 20th November). The Class 20 locomotive provided the motive power for the high speed test, and with the light load of the carriage was very quick in reaching the desired speed. Day 3 (Wednesday 21st November) was booked as spare in case there were any issues earlier in the week. In the event this was used for additional mileage accumulation.

The following amateur footage shows the test train leaving the outskirts of Loughborough during one of the high speed runs.

The GCR was chosen as it has relatively straight and even track; ideal conditions for undertaking brake calculations and measuring vertical and lateral accelerations. The railway had been granted a derogation from the Office of Rail Regulation  for undertaking the high speed test. The Institute of Railway Research carried out the safety assurance work for the carriage and conducted the instrumentation and testing of the vehicle with support from London Underground and Festiniog Railway representatives.

Met 353 – Completion of restoration

The gleaming carriage, finished with gold leaf and carrying no fewer than ten coats of varnish, bears little resemblance to the sorry-looking hulk which arrived at Porthmadog, North Wales in August 2011 after being used as a garden shed.

Craftsmen at the Ffestiniog and Welsh Highland Railway this week completed to schedule the 15-month, £200,000 restoration. The carriage travelled from Boston Lodge Works and over Britannia Bridge in Porthmadog before being loaded onto a waiting lorry for transport to the Great Central Railway in Loughborough. Next week the carriage will undergo dynamic testing on the GCR as it is too large to be tested on the narrow gauge F&WHR.

Restoring Met 353 – Testing of safety critical components

Wheel Sets

During May safety critical components such as the draw hooks and wheelsets were carefully cleaned and NDT tested (Non Destructive Testing). This important procedure highlights any defects within metalwork that could later lead to failure of the part in service. Thankfully the majority of components passed the examination, however a number of brake block carriers failed and replacements duly sourced. When complete the carriage will have a dual (air and vacuum) braking system fitted, allowing it to be compatible with a range of heritage rolling stock. Interestingly, a number of ex London Underground A-Stock components have been recovered for re-use on the carriage braking system. Items include an auxiliary reservoir tank and two pressure gauges formally fitted to 6136 and 5136.

The profile of the wheels was checked last year and the shape found to be fairly good – A moderate amount of wear was discovered but well within intervention limits. There are currently no plans to re-profile the wheels (now close to P8) and they should be good for another 100,000 miles!

Restoring Met 353 – Loan of carriage door

Carriage Door

It can be very difficult to undertake an accurate and faithful restoration if original components are missing, or the information required to reproduce them unknown. One such challenge has been to identify the type of door latches once fitted to Met353. As none of the originals survived it was most fortuitous to recently find a complete door from another early Metropolitan Railway carriage, Met212 built by Ashbury in 1881. This has been kindly loaned to the project team by the Quainton Railway Society (QRS) and the detailed information gained from inspecting this example is proving invaluable to the build. After some careful cleaning and dismantling, it quickly became apparent the lock mechanism was designed by Edwin Robert Wethered, an inventor once based in Woolwich, London. It closely matches his patent: 407,268 submitted in 1889.

Notes: Met212 was one of the last 8-wheeled stock carriages to be operated by the Metropolitan Railway. It was later modified for use as a sleet clearing vehicle and survived into London Passenger Transport Board (LPTB) ownership in 1933. Once withdrawn from railway use, the carriage body was grounded next to staff allotments alongside Aylesbury train station. A door was rescued by QRS before the carriage was finally broken up in 1967.

Restoring Met353 – A craftsman’s perspective

One of the first challenges has been to repair the teak frame of the carriage; and undo the damage caused by many decades of human use and exposure to the elements. Surprisingly, in spite of being a timber frame, most of the damage has been caused by rust.

In the 1890s, the normal way to construct the wooden framework of a railway carriage was to use traditional joints such as ‘mortise and tenon’ and ‘lap joints’. In the absence of any effective glue, steel woodscrews were used to keep these joints together. Where further reinforcement was required  steel brackets were added, held in place by bolts or coachscrews. Over time these steel screws and bolts have rusted, and as they rusted they have caused considerable damage.

As the screws and bolts slowly rusted, the expanding corrosion inexorably forced the wood apart, bending and splitting it. In some places, such as the tops of the corner posts, the fixings have split and splayed the timber in every possible direction.

To repair this sort of damage, the rusty fixings must first be carefully removed, the splits stabilised, holes plugged, and finally the surface replaced with a structural veneer of sound material. Once complete, the repair will be visually unobtrusive and should last for many years.

Collecting for 2013 – Caledonian Road station’s whiteboard artist

 

 

It’s not every London Underground worker who has a song written and recorded about her, but that’s what has happened to Kim Kalan.

The bubbly customer service assistant at Caledonian Road station, on the Piccadilly line, has been brightening up the ticket hall with her intricate whiteboard drawings  – with an accompanying cheerful message for passengers.

As well as being praised by customers, Kim’s colourful drawings were noticed by local musician Eoin Quiery. He was so impressed he decided a write a song about her, which has been recorded on the latest album made by his acoustic rock band, Burning Wheel.

Called Kimmie Song, it can also be found on YouTube and other social networking sites.

It all began in a small way,” said self-taught artist Kim. “When we used to display notices to the public about delays or other problems, I started to put little drawings on them to brighten them up.”

She then moved on to the whiteboard drawings, working on them in her breaks and often coming in early before her shift begins.

Using white board markers she covers a wide range of subjects, ranging from the Mona Lisa to the World Cup and Armistice Day, always coming up with something special to mark Christmas, Easter and other seasonal occasions.

“I do it purely to make the day better for my customers,” said Kim, who affectionately refers to them as “my lovelies.”

She added: “What’s important to me is the positive effect my drawings and messages have on people; I’m not after any sort of recognition.”

Passengers regularly praise her drawings, including a local professional artist who said he could not do what she does with the white board markers. Other passengers have asked her to draw portraits of them.

Asked what she thought when she found out that Eoin Quiery had written a song about her, she said: “I was very surprised. How often do people get a song written about them?”

Kim, whose mother Sandra works in the station’s ticket office, also writes science fiction in her spare time. Her first fantasy book is complete and Kim is currently waiting for an agent.

My ambition is to become a full-time writer,” she said. “In the meantime I will continue with my ticket hall drawings and am so glad that they have met with such a brilliant response from customers.”

Collecting for 2013 – Oyster card holder swap shop

What does your Oyster card holder mean to you? Did you get it for free, buy it especially, or receive it as a gift? Do you use it as a wallet or just to keep your Oyster card safe?

Oyster wallets come in all colours, patterns and styles, from simple plastic holders to fancy leather and fabric cases. Companies across the capital have created their own holders as forms of advertising, with wallets being handed out all over the city every week.

As part of the LU150 celebrations, and in partnership with Andy Wallace from Transport for London, we went out to Acton Town earlier in March to find out more about what people store their Oyster cards in. If they were willing, we asked members of the public to swap their current holders for a new one, collecting the story behind the significance of the ones they donated.

Some of the stories were great, from wallets people have had since Oyster started in 2001, to pretty ones given as gifts, as well as holders purchased overseas. We’ve so far collected around 70 wallets for the Museum’s collection, all with their own great stories and anecdotes attached.

If you’d like to donate your Oyster card holder to the Museum, get in touch!
