Heat treatment of rail welded joints in induction units
The technology and equipment used in Russia for the heat treatment and welding (flash butt, thermit, arc bath) of rails is presented. Induction units are used for heat hardening of rail welded joints; the specification for an induction unit is given. Recommendations have been drawn up for welded rails (IIW/IIS Doc. III-1127-98) and for welded rails with differentiated heat treatment of joints (IIW/IIS III-1128-98), in which strength, ductility and rectilinearity of joints, and fields of applications for rails, welded by different processes, are specified.

Effect of rare earth on the internal friction spectrum of the tread area of the BNb rail steel
The Snoek-Ke-Koster (SKK) peaks (internal friction) of specimens of BNb and BNbRE rail steel (laid for one year after hot rolling and RT deformed after treatment at 700Â°C for 30 min.) were investigated. Peaks were found to differ, with the former rail steel being higher (+20Â°C) and wider; a Snoek peak was found in BNbRE but not in BNb. SKK peaks in deformed specimens of both steels were similar. Tests on these steels in use for over two years were considerably different from one year old specimens. [In Chinese]

Stretched rail gaps
A newly patented technique for dealing with broken rails (US6515249), developed by Harsco Track Technologies (USA), is briefly described. In order not to introduce a different 'neutral rail temperature' (the temperature at which the rail was originally installed and tensioned) by the introduction of a repair strip, Harsco cut out the defect with the minimum of rail loss, machine the rail ends to match, then pull the rails until they meet; the final gap is secured with a single weld. A 300 tonne rail puller is employed.

Following the crash at Hatfield in October 2000, UK state aid to the railways accelerated. By 2001 railway aid amounted to nearly two-thirds of all subsidies, having risen from 3.3bn euros in 1997 to 6.8bn euros in 2001.

Rail authority considers reinstating shelved west coast main line projects
The Strategic Rail Authority is examining the possibility of going ahead with the remodelling of Rugby station and the construction of more tracks between Rugby and Stafford as part of the prime work to be undertaken on the west coast main line upgrade. The SRA is of the opinion that the whole project will not work if elements are removed, such as the alleviation of the severe bottleneck at Rugby. The two latter elements of the project were to be postponed, according to Tom Winsor, the rail regulator, in order to save money. This is being reviewed.

'Co-opetition' across national borders vital to future of Europe's high-speed railway services
The need for national rail companies to persuade their governments to invest in the doubling of Europe's high speed network by 2010 is considered. In order to win passengers from airlines on longer-distance routes commanding higher rail fares, an integrated service is required, which will rely on compatible technologies, safety rules and allowing the use of lines by competing companies. SNCF (France), Ferrovie dello Stato (Italy) and Deutsche Bahn (Germany) are jointly commissioning a high speed train.

Laser generation has been combined with air coupled ultrasonic detection to form a technique capable of locating elusive rail discontinuities, such as vertical split head and rail base cracks. Results of tests carried out at the Rail Defect Test Facility at the U.S. Transportation Technology Center are reported. 100% detection of vertical split head defects and 90% of rail base cracks were achieved. Mounted on a railway pushcart, the noncontact and remote nature of the device allows flexible and high speed testing. Details of the experiments and equipment are presented.

On propagation of short rolling contact fatigue cracks
The numerical modelling and analysis of short crack behaviour in rails during rolling contact fatigue loading was investigated. Factors that influence the fatigue propagation of short surface-breaking cracks (head checks) in rails were assessed. A parameterised finite element (FE) model for the rolling-sliding contact of a cylinder on a semi-infinite half space, with a short surface breaking crack, is presented. It is used in linear-elastic and elastic-plastic FE calculations for short crack propagation, together with fracture mechanics theory. Crack length and orientation, crack face friction, and coefficient of surface friction near the contact load were varied. The FE model is verified using four examples from the literature.

From 2010 the new train would replace the French TGVs, the German ICEs and the Italian ETR 500s, but trains for specific countries would have features to match their electricification, signalling and passenger requirements. Common components would ease the travel of trains through different rail networks as well as reduce costs.

Deutsche Bahn skidding off the rails
A recent survey has revealed that the state-owned rail company is the German nation's most unpopular company. Deutsche Bahn passenger numbers have fallen 10% during the first quarter of 2003, with income from longer journeys down 14%. The change in attitude comes as a result of the introduction in 2002 of an unpopular pricing structure and technical hitches on the Frankfurt-Cologne high speed link which have led to increasing nationwide delays. Former passengers are using their cars or are taking advantage of cheap air fares.

Watch out for bad vibes
Researchers at the University of Illinois at Urbana-Champaign have developed a technique for measuring rail stress by forcing it to vibrate and measuring the size of the vibrations. The frequency of the induced vibrations is related to the stress in the rail. Rail is laid so that it is slightly compressed when cold. During hot weather this stress rises as the rail expands. Over a critical level the rail buckles as the train travels over it. At sites of large daily temperature fluctuations, rail can become sensitised which results in overstressing at lower temperatures. The test equipment has an electromagnetic shaker operating at 200 hertz which is attached to a short section of free rail (by removing two clips). A laser detector measures the vibrations at 10 cm intervals along the unclipped section of rail, to calculate the stress in the rail. Variables, such as sleeper type, do not affect the wavelength.

The new audit system for rail safety systems being introduced by the Railway Safety and Standards Body (RSSB) has been labelled as fragmented and bureaucratic. RSSB is to accredit companies doing safety audits, and train operating companies have a year to transfer to the new system. The present standards and audit body, Railway Safety, has advised the Health and Safety Executive that the proposals could lead to audit companies not giving 'bad news' in case they lose business, and they consider that the safety of the rail network should be treated as a whole, not blocks, to ensure firstly, that no black holes exist at operator interfaces and secondly, that best practice can be shared.

Driverless freight train
The CargoMover, developed by Siemens, uses a combination of radar, lasers and GSM mobile data systems to direct itself automatically through a route using gaps between scheduled passenger and freight trains. CargoMover offers flexibility that can cope with small consignments at short notice, offering a real alternative to road transport. The system is under test at the Siemens test track in Wildenrath, Germany. Further details are given.

Network Rail puts pressure on contractors
Network Rail is taking back the maintenance contract for line from west of London Paddington Station through to Reading. The section covers all types of services and is a bottleneck. The maintenance carried out by Network Rail will act as a sample to ensure that the other 19 maintenance contracts it awards are known to be value for money, and also to see how new regulations have a knock-on effect on costs and disruption.

Eurostar train breaks British rail speed record
In a test run on a section of the Channel tunnel rail link, a Eurostar train achieved 208 mph (334.7 kph), breaking the UK rail speed record. The first section of the rail link is to be officially opened at the end of September. It is expected to reduce travelling time between London and Paris to just over two and half hours, and to Brussels to just over two and a quarter hours.

Rail chief defends plan to scale back work on rural lines
The Strategic Rail Authority is not recommending the closure of lightly-used rural lines, but the scaling back of maintenance on them in order to liberate funds for mainline and main secondary routes, London and the south east. It was stressed that the proposals are open to discussion, but slightly slower services and more temporary speed restrictions on rural, freight and some secondary lines is not seen as a problem.
