£190m Tube and Crossrail escalator deal up for grabs

Crossrail and Transport for London have teamed up to find a builder for over 100 escalators for the underground transport network in central London. It will be the biggest order ever placed for station escalators and both transport companies hope to make big savings from economies of scale.

The cost of designing, building and maintaining a single escalator is over £1m. About 60 escalators will be required for the Crossrail stations in central London with around 45 escalators required for London Underground’s major escalator replacement programme. The contract is also open to the whole TfL group and could be extended further to meet the future needs of Docklands Light Railway, London Overground as well as Tube maintenance firm Tube Lines.

Andy Mitchell, Crossrail Programme Director, said: “2011 marks the 100th anniversary of the first escalator being installed on the Tube network at Earl’s Court. “During the coming years, Crossrail and London Underground could need over 100 new escalators and this contract is likely to be the UK’s largest single order for station escalators.

A joint procurement process is being undertaken by Crossrail and TfL with the aim of achieving significant cost savings that would not otherwise be realised if separate smaller orders were placed.”

Under this contract, installation of new escalators for the Tube network is due to begin in late 2013 with work underway from 2015 at the Crossrail stations. The invitation to tender will be issued later this year. The closing date for expressions of interest is 13 July 2011.

Atkins lands major comms contract on London Underground

Atkins has been appointed by VINCI BAM Nuttall JV to design, install, test and commission telecommunications assets at London’s Victoria Underground station, as part of the major programme to the station, which is one of London’s busiest interchanges, used by over 80 million passengers a year.

Atkins will deliver a range of works, including providing the final construction design, design co-ordination, coordinated fabrication drawings, supply of installation labour and delivery of equipment necessary to undertake complete installations of new Station Communication Systems for the Victoria Station Upgrade Project.

Atkins will deliver a complete suite of telecommunications services and Douglas McCormick, Managing Director for Atkins’ Rail business, said Atkins’ capabilities will ensure this contract is delivered to the highest level. “Atkins has a very successful history delivering telecommunication and station redevelopment projects, and this contract will ensure that Victoria tube station is both a leading and user friendly rail station,” said Mr McCormick.

The contract at Victoria Station, which is undergoing a £700m redevelopment , further strengthens the company’s extensive underground portfolio. “Our teams’ diverse background and project personalisation further proves our capabilities, and our ability to deliver in different rail environments,” said Mr McCormick.

Atkins’ role is expected to be completed in June 2016 with the overall London Victoria Underground Station project due for completion by 2018.

Major strengthening programme completed on London Underground

As part of a major strengthening programme on the London Underground, an innovative solution was required to provide long term strengthening to over 90 cast iron beams.

Following an extensive design and specification process, the result is the UK’s largest ever application of ultra high modulus composite reinforcement, supplied by global building product manufacturer Sika and national specialist contractor, CRL (Concrete Repairs LTD).

Covered Ways CW17 and CW20 are on either side of Embankment Station on the District line, built in the 19th Century using ‘cut and cover’ techniques. The covered ways carry the weight of Embankment Gardens situated above the District line tracks.

Although the cast iron beams were assessed and found to be adequate to support the intended loadings and in a good serviceable condition, there was serious concern that the cast iron beams could be overstressed, under unforeseen overloading. London Underground undertook a feasibility study to determine the best all round solution to complete this strengthening. Both economically and logistically the best solution was to strengthen the beams in-situ.

London Underground had to ensure the chosen repair solution would have minimal impact on the tunnel headroom and could be installed during Engineering Hours (overnight when there is no train service) so as to cause no disruption to the District and Circle line services.

With a reinforced steel element deemed too thick to be a viable option, a system that was thin yet extremely tough was required. The solution to the challenge lay with Sika CarboDur UHM and a well planned application procedure. An Ultra High Modulus Carbon Fibre Reinforced Polymer (CFRP) system, Sika CarboDur UHM is designed for high performance and demanding reinforcement applications.

The plates, measuring 7.3m long, 200mm wide (2no per beam) and maximum 4.7mm thick and offering exceptional reinforcing capability, proved the ideal solution.

With over 1,300mtr of Sika Carbodur UHM plates applied, it has marked the UK’s largest ever project to use ultra high modulus composite. Specialist contractor, Contrete Repairs Limited carried out the skilled application, having been appointed by LU Framework Contractor, Clancy Docwra.

The process began with each beam, measuring 7.5m long and 0.5m wide, cleaned using a powerful grit blasting technique that removed grease, oil, rust and any other contaminants which could reduce adhesion.

Once dried, a coat of SikaCor-EG 1 primer was applied, followed by the application of a resin to prepare the surface. Ensuring secure, reliable attachment of the Sika CarboDur Plates, SikaDur structural epoxy adhesive was then applied to both the underside of the cast iron and the plate itself.

When placing the plate into position, full contact of the adhesive to the two surfaces guaranteed a long-term bond was achieved before a series of temporary supports were put in place whilst the adhesive cured. The excellent performance of the adhesive allowed installation to carry on throughout the winter months when low temperatures and condensation can cause problems for other adhesives.

To minimise service disruption on the District and Circle lines, the entire process had to be completed during Engineering Hours (overnight when there is no train service) and was scheduled to be delivered in a series of shifts between 1am and 5am, over a period of six months. In each shift, the project team had to erect scaffolding, transport the equipment and materials to the desired location and clean and prepare the beams before applying the Sika CarboDur UHM plates and temporary supports.

The supports, scaffolding and equipment was then removed to allow the underground to reopen. “The Sika solution proved the most practical method to strengthen the beams. With severely restricted access, in terms of both space available and the four hour window in which we could work, its ease of application – combined with a carefully managed schedule – enabled the project to be delivered within the allotted timeframe,” said Olu Ogunwale, Contracts Manager at Concrete Repairs.

The bespoke Pre-Preg manufacturing process used to create the UHM plates also ensured maximum efficiency with the creation of homogenous individual plates to the exact design dimensions in terms of length, width and thickness.

At Embankment, this included specifically designed tapers in the end of the plates to reduce peel stresses to absolute minimum, inclusion of a small cut out in the end of the plate for increased tolerance around a downstand in the soffit of the cast iron, and fully applied fire protection to all exposed surfaces of the plate.

By overcoming the extreme time and spatial constraints of the London Underground, the client, contractors and material suppliers demonstrated outstanding workmanship and expertise to complete the project on time and on budget. Delivered over a six month period, the project was successfully finished to the highest standard with the contractors reinforcing an average of two beams per night on-site.

Thanks to a well-organised, detailed process, this length of London Underground was able to remain fully operational throughout, with the service’s passengers entirely unaware of the vital work being undertaken.

Oyster card users will soon see London 2012 posters on the Tube

The London Underground transit system will soon be decorated differently, thanks to a London 2012 Olympic poster project.

Famous artists such as Tracey Emin, Howard Hodgkin and Martin Creed will be designing pieces of artwork for Oyster card users and people travelling on the Tube to see.

Twelve artists in total have been selected to take part in the project, having been whittled down from a longlist of 100. They will be able to produce a poster, which will be displayed on the London Underground transit system, in any style they want, as long as it illustrates something associated with the Olympic or Paralympic Games.

"I wanted to do this because it would be fun and London 2012 is something to celebrate," said Turner Prize nominee Emin.

The recent walkouts on the Tube have led to renewed fears strike action could plague the London Olympic Games next year, as it would be the prime opportunity for workers to raise awareness of their cause.

London underground rail strikes called off

London underground drivers have called off a series of strikes due next week after a sacked worker at the centre of a disciplinary row was reinstated by operator London Underground, their union said on Thursday.

London Underground had said the worker was dismissed for alleged unacceptable behaviour towards staff but the Rail, Maritime and Transport RMT.L union said he had been fired because of his union links.

He was reinstated by the company after an employment tribunal said he was unfairly fired. The RMT said staff would not go ahead with walkouts scheduled for next Monday, Wednesday and Friday.

Millions of commuters would have been affected if the industrial action had gone ahead. Industrial action would also have coincided with the second week of the Wimbledon tennis championships in south-west London.

Is This the London Tube Train of the Future?

According to Railway Gazette, this could be what the London Underground trains look like in the future.



Siemens unveiled this concept for consideration for the next generation of tube trains. The current rolling stock is undergoing an upgrade now. And as The Londonist points out, aside from the distinctive circular operators cab, this vision isn’t all that different from the newer cars.

Siemens does point out this concept design would increase capacity by 11 percent, impressive, considering one of the limitations of London’s system are the tight tunnels, which constrict car height, Many of the the system’s eponymous tubes were originally designed and built well over 100 years ago.

That's Brilliant. That could easily be an 'Ident' for a TV Channel.

Don't think he created it. If you look at the myriad of video's he posts it looks like he trolls Youtube and elsewhere looking for anything London related and posts. Same too with news stories. Getting a bit annoying actually as nothing else appears to be here and the same thing often gets posted to 2 or 3 threads.
