It’s been a lazy Sunday here at Bigland Towers. The pair of us (well, the three of us really, as Jet our cat was in no rush to do anything either) had a slow morning drinking coffee, catching up on the news and watching the world go by. The only thing missing was having a Sunday newspaper spread out on the bed, but those days are long gone. I can’t think of the last time I bought one. Partly because there’s no local newsagent for miles, but also because the world’s moved online and I can pick and choose from loads of different news sources now. The difficulty is finding a reliable one! Talking of which, I was planning to dissect Simon Jenkin’s latest fact-free rant about HS2 in Saturday’s Guardian, but that can wait until another day. It’ll have exactly the same effect as all his other rants going back a decade. In other words, Zilch. Instead, I spent a couple of hours researching, reading through the minutes of last months Transport Select Committee meeting which heard from Birmingham’s Mayor, Andy Street and also HS2’s CEO, Mark Thurston. When you read their words verbatim it becomes obvious just how lazy the media reporting of their words was. I’ll be including excerpts when I fillet Jenkins rant.

The afternoon was far less lazy. Dawn went into ‘Domestic Goddess mode and spent several hours in the kitchen, experimenting with cake-baking recipes in order to perfect a cake for a friend’s wedding whilst I retreated to the office to sort out more old pictures. I have to admit the smells coming from the kitchen were divine. Dee’s a brilliant cook and really enjoys baking. It’s not something I’ve ever got into personally, my forte is more Asian and starters and main course dishes rather than sweets and desserts.

The day wasn’t all about food, we did both manage to get out for a stroll, even if it wasn’t far, just through our local woods along the promenade overlooking the Calder valley and thence around Savile Park, but it was good to be able to feel virtuous by hitting our daily exercise marks.

Now we’re home for another quiet evening, but as it’s going to be a busy week that’s hardly a problem. So, I’m going to leave you with today’s picture which is taken from another of the batch of old slides taken in the USA back in 1990. No animals today, this is very much a man-made structure. I took this shot of Big Creek bridge on State Highway 1 on the California coast on the 25th October 1990.

Opened in 1938, this graceful bridge is a 589 feet long, 24 feet wide open spandrel, concrete deck arch structure designed by Christian Theophil Gutleben. Each span is 178 feet wide and 65 feet above ground level. It’s quite an impressive sight when you first glimpse it as you approach along the coast from the South, but then the California coast road is a lovely route with several similar structures. There parking places at either end so that you can stop, admire the bridge, sea or cliffs and take photographs.

Wow! After such a long spell of absolutely perishing weather we’ve actually had a day where the temperature made it into double figures at the right end of the thermometer! Being able to walk without being swaddled in scarves, hats and gloves made an extremely pleasant change – as did the fact the heavy rain we’d had the other day had washed almost all of the snow away and the day stayed dry. One was almost tempted to believe Spring may be on the way but it’s going to take more than one day of mild weather to convince me of that. Even so, I’m beginning to think it might be time to fettle the front garden and clear up the garden bench in the hope that we can spend less time cooped up indoors…

Still, whilst we are, I have plenty to keep me occupied. I’ve a stack of articles to write and pictures to scan. One of the latest batch forms today’s picture. I took this shot of the Albert Bridge in London on the 14th January 2001 which was a crisp clear winter’s day with some glorious low winter sunshine. The Albert Bridge is of a rather unique design, although it’s been modified a couple of times since it opened in 1873. Along with Tower Bridge to the East it shares the distinction of being one of only two Thames road bridges that have never been replaced.

Seen here from the North Bank of the Thames, the slender Albert Bridge is an attractive and graceful structure.

When I’ve finished editing the newest scans from London later this week you’ll be able to find them in this gallery on my Zenfolio picture library website.

Rolling (ish) blog: London travels…

10:40.

I’m at Twickenham station after completing the first assignment with Network Rail’s ASPRO (Asset Protection) team where we visit the project you can see in the background to this picture.

This is the new station building that also contains flats and shops. It’s a complex project built astride the operational railway that’s due for completion next year. We’re now off to have a look at a similar project in Kew.

13:09.

Wow! That was interesting. You get to go to all sorts of places in this job. This triangular site is bounded by three railway lines. On one of them sits Kew Bridge station (just off the the left of this picture). Around the triangle’s a vast housing development that also includes Brentford Town’s new 17,000 seat stadium. It was originally planned to be 20,000 but this would have overhung the operational railway and proved to be difficult to maintain, so was scaled back.

15:52.

Next up was Vauxhall. Wait till you see some of the other pictures I took from the roof of this new 27 storey development!

Like this, looking at Vauxhall station in a way you never normally get to see it – unless you’re in a plane!

DG327638CROP

16:20.

Now I’m in Stratford, an area I knew well as I lived and worked near here for 11 years. I have to say, where we are now I wouldn’t recognise at all. The only thing that still remains is the railway from Stratford heading up to Lea Bridge. Everywhere you look new housing has sprung up.

18:49.

After a long, hot and sweaty day I’m heading back North on LNER’s 18:33 to Bradford Forster Sq. This is still worked by a Class 91 and Mk4 set, but they’re showing their age. This set is missing coach D, which is causing a few problems. Plus, both ovens in the buffet are kaput and the PA’s on the blink!. That said, the Train Manager’s doing an excellent job keeping passengers informed. He’s pointed out that the first stop is Stevenage, where (normally) at least 100 people will leave the train, so there should be plenty of seats available (he was right by the way).

21:05.

I’m on my last leg, if not my last legs! The journey up to Leeds was pretty good. I managed to get a bit of work done on the train but also had time to collect my thoughts for a bit and enjoy the scenery for a while, which is a rare treat.

Now I’m on Northern’s 21:08 from Leeds to Huddersfield via Halifax which is made up of a two-car 144 and 150 lash-up which were joined in the station as I arrived. I suspect they’re heading to Huddersfield for stabling overnight. For old times sake I’m travelling on 144009 as Pacer withdrawals start this month and soon, they’ll be all gone.

Siemens opens a rail bogie service centre in Lincoln

Engineering, Eurostar, Lincoln, Railways, Siemens

On Friday 23rd I attended the official opening of Siemens new rail bogie service centre which has been built at their existing gas turbine manufacturing facility  in Lincoln. The facility allows Siemens to carry out bogie overhauls ‘in house’.

A disused building dating from 1874 has been converted for the purpose at a cost of £8 million. Work involved relaying and strengthening 5000 square metres of floor space before installing cranes and other equipment needed to overhaul the bogies. 32 people are currently employed at the facility which began production in September, overhauling spare bogies for the Eurostar e320 trains built by the company. Bogies from the Desiro City fleet of Class 700/707/717 trains will also be overhauled on the site, which has room to be expanded if demand requires it.

Here’s a selection of pictures from my visit.

DG313311copy

A bogie off a Eurostar e320 that’s just been unloaded onto the bogie assessment area. Here a condition assessment is undertaken before it’s moved into the cleaning booth behind it. In the booth the bogie is cleaned using a ‘dry ice’ blasting technique using a solid form of carbon dioxide which is accelerated in a pressurised air stream. This allows the bogie to be cleaned without using toxic chemicals or water, thus cutting down on pollution.

DG313321crop

After cleaning, the bogies are placed on these adjustable jacks to be stripped.

DG313325crop

A view of one side of the shed, the bogie stripping area is on the right of the picture. On the left is the UAT station, the axle bearing press station and the wheelset rebuild station.

DG313327crop

The axle blasting area is where the wheelsets are mechanically cleaned to remove any painted areas. The Finnblast machine is a fully automated system that works by blasting an abrasive air mixture through the nozzle in the blasting chamber with the compressed air acting as the driving force. The speed of the abrasive when charging from the nozzle is about 200 metres per second.

The wheelset disassembly area. Here the axlebox housings and bearings will be removed using the hydraulic bearing puller in the background.

No caption needed!

The axle bearing press station, where the bearings are fitted back onto the axle using the hydraulic press that you can see in the background.

DG313400crop

The bogie press. This is where the rebuilt bogie is subjected to pressing. This reflects the weight characteristic of the particular car a pair of bogies will run beneath and it’s a fully automated process. Using measurements taken in specific locations during the bogie overhaul process it will press against the agreed criteria. The results are automatically generated from the machine. These results must fall within the agreed tolerance range for the bogie to pass.

DG313412crop

All set up and ready to go. Overhauled Eurostar e320 bogies await return.

A FAVOUR.

SWT Convert their Class 455 fleet to AC traction

21 Thursday May 2015

Class 455, Engineering, Rail Investment, South West Trains

Yesterday I visited South West Trains Wimbledon Park depot to see the second of their Class 455 fleet being converted to AC traction & hear Christian Roth, Engineering Director for South West Trains, who was on hand to talk about the reasons for the programme.

Converting the 91 strong fleet from DC to AC traction will cost £38m. It’s funded jointly by owners Porterbrook and the Department of Transport (with DfT stumping up a 3rd of the cost). The project has a number of aims & advantages, which are;

AC traction motors give the train regenerative braking capability saving £2m a year in electricity bills and lessening wear and tear on the braking equipment compared to pure friction braking.

They’ll have new Wheel Slip Protection (WSP) system which is based on modern, European Algorithms rather than the legacy BR system the 30yr old units have now. This will reduce wheel flats during the leaf fall season & help extend the exam period from 10,000 miles to 15,000 miles. The new A/c motors are also less prone to damage from snow ingress.

Christian explained that the cost of overhauling a Class 455 is around £150,000-£200,000, so extending that period by 1/3 on a 91 strong fleet is a not insignificant saving. It’s not hard to see that there are advantages to carrying out the conversion. But the most significant one isn’t to do with the 455s at all…

Extending the maintenance regime frees up space at Wimbledon Park allowing it to become home to SWTs next fleet – The 30×5 car Class 707 Desiro City trains from Siemens. This £210m investment is vital to tackle growth & overcrowding on the SW network. Without the space at Wimbledon Park a new depot would have been necessary, significantly altering the finances of the Class 707 project. After Christian’s briefing we went to inspect the second unit to be converted (5870) which was sitting inside the Inspection shed on 12 road. Here’s a look at the work.

The first unit to be converted (5732) was also done at Wimbledon Park (in exactly the same place) back in 2014. Here it is;

DG184054. First AC Class 455 conversion.  Wimbledon Park depot. 30.6.14.

Right now 5732 is undergoing tests between Bournemouth & Weymouth. Once 5870 is completed (which is expected to be 19th June) it’ll also be sent to Bournemouth & the two trains will carry out further tests such as passing at speed & running as 8-cars.

Christian told us that the testing programme is going well with the equipment performing “better than expected”
Once testing is finished by the end of July the converted trains will enter service & free up others for the programme which will be carried out at the Arriva train depot at Eastleigh, starting at the end of August/ beginning of September. Three trains per week will be converted until the programme is complete in August 2016.
So, if you’re an aficianado of the 1930s designed English Electric EE507 traction motors, you’ve got little more than a year to hear these long serving beasts in action under the 455s…

Here’s another fan with the EE507s taken out of 5870;
