Crossrail rival 'is needless distraction'
The Superlink project, a cross-London rail route from Reading/Basingstoke to Southend/Ipswich, proposed by a former senior manager at British Rail, John Prideaux, and a rail consultant, Michael Schabas, has been dismissed by government and railway groups. It is claimed that Superlink would carry four times as many passengers, take more pressure from the Tube and road network, generate more income and would be easier to fund. The project would include a link to Stansted airport.

Tube contractors told to put profits into maintenance
Following the announcement of Â£93M in profits earned between the Tubelines and Metronet consortia over the first full year of public-private partnership, London Underground is insisting that the contractors plough the majority of profits into improved underground system maintenance. London Underground and Transport for London consider the underground maintenance poor enough to look beyond the consortia in awarding new contracts.

The incidence and causes of rolling contact fatigue (RCF) in rails are summarised. Costing the European railway industry around 300M euros per annum for the removal and replacement of rail plus associated costs, methods of detecting and preventing RCF (inspection, grinding) are briefly described. The report by Professor Rod Smith at Imperial College, commissioned by the Railway Safety Research Programme following the derailment at Hatfield, 'Rolling contact fatigue of Rail', gives a review of the issues surrounding RCF and suggests areas for further research. Areas identified for future work are: risk modelling of the different factors and consequences of RCF to allow the prioritisation of control measures and to manage the risks; the development of models of the physical processes leading to the initiation and propagation of RCF cracks, and their likelihood of developing into fractures; wheel/rail lubrication processes; the acoustic monitoring of rail conditions; and wheel impact measurement.

The sound of safety
The use of the G-Scan inspection system, for the detection of cracks deep within rail welds, is described. The equipment, developed by Guided Ultrasonics, an Imperial College spinout company, is based on a technique originated by the Research Centre in Nondestructive Evaluation (RCNDE) at the College. The system employs a guided wave travelling along the rail, allowing it to scan 50 m of rail in both directions from a single inspection point. Internal and surface breaking cracks can be identified in the same test. In trials the system has shown it can produce a good correlation between test results and the breaking strength of thermit welds. Full product approval is being applied for this summer. RCNDE are also developing a testing device based on high frequency (20 - 100 kHz) Rayleigh waves for the detailed inspection of rail close to the transducer. This could be used to inspect composites and metals, such as ship, aircraft and nuclear power plant components. The waves cause the material to vibrate, crack edges rubbing together create heat which is identified using a thermal imaging camera. This method originated in the USA but has not previously been harnessed into a working inspection system.

Effect of local induction heat treatment on the induced residual stresses in the web region of a welded rail
The effects of local induction heat treatments (IHT) on the microstructure and on the resultant tensile residual strsses in the web region of flash butt welded rail (0.59%C, 0.27%Si, 0.01%S, 0.008%P, 0.02%Cr, 0.01%Ni) were studied. Microscopic studies were undertaken on the welded zone in the head, the web and the base parts of the rail. Dilatory specimens of base metal were heat treated under different IHT cycles and phase transformations and length changes obtained. The effects of local IHT on the residual stress field in the welded zone were investigated using finite element analysis. A local induction hardening and tempering heat treatment to reduce residual stresses in the web region of a welded rail is proposed.

Improvements in noncontact ultrasonic testing of rails by the discrete wavelet transform
The discrete wavelet transform is applied to two different configurations of noncontact ultrasonic rail testing. The first hybrid laser/air coupled configuration is suitable for detecting transverse surface cracks, and the second, a through transmission air coupled system, is for the detection of longitudinal internal cracks. It is shown that discrete wavelet transform processing can substantially improve the noise filtering and compression performance of both systems. The role the mother wavelet shape plays in the analysis is considered in detail.

Long range inspection of rail using guided waves
The guided waves modes that can exist in a rail are found using 2D FEA, and their interaction with a variety of features and defects is investigated with 3D time-marching FE models. Results from a prototype testing system are compared to FE predictions. Sensitivity to transverse defects and defects in alumino-thermic welds is demonstrated.

Groundwork for rail flaw detection using ultrasonic phased array inspection.
An increase in detectability of internal transverse flaws in rail track was apparent when the ultrasonic beam was orientated off the longitudinal axis of the rail. To test this phenomenon, artificial reflectors were used to help define the extent of material â€˜seenâ€™ by ultrasonic beams and to determine how surface curvature may affect inspection. Four rail samples were studied: three worn sections with internal defects and a new rail with an as-made profile. Results are presented and discussed.

News in brief
A consultation amongst the UK rail industry on the standardisation of technical and other systems across the whole European network has been launched by the Department for Transport. The consultation is a forerunner to a future European directive that is to create a single market for goods and services. The first rail interoperability directive has already been implemented in the UK, concerning new and upgraded high speed infrastructure and rolling stock. Deadline for consultation responses is 16th April.

Ministers 'close to rail shuttle ruling'
Ministerial approval is expected soon on the Â£10M project put forward by Central Railway to operate freight shuttle trains between Liverpool and northern France. A government bill is required to construct a new railway line, using part of the trackbed of the old Great Central railway from Marylebone station to the north east. The line would carry freight trains with continental European gauges (wider and higher than the UK) through the Channel tunnel. The piggy-back service is not possible on British railways as a result of loading gauge constraints, and bridge and tunnel clearances. Central Railway has been awaiting a decision for three years.

Raffarin sets infrastructure priorities
50 major rail infrastructure projects over the next 20 years, intended to help sustain the national economy, create employment and maintain France's competitive position in Europe, were confirmed by prime minister Jean-Pierre Raffarin at the inter-ministerial planning and development committee in Paris last December. The projects include 8 high speed schemes, and a new agency is to be set up to fund infrastructure investment. The eight high speed projects and 8 major upgrades on main lines are detailed (map included), and funding reforms are discussed.

Crossrail to give economy Â£19bn boost, say studies
Ahead of the official report for the transport secretary on the Crossrail project, studies for the mayor of London have predicted that building Crossrail will generate Â£19bn over 30 years for the UK economy - Â£8bn from people able to access central London easily, Â£3bn from a rise in output, and Â£8bn from saving in journey times. The London mayor estimates the cost of building Crossrail to be Â£7bn, not Â£10bn as reported by the Treasury.

Guided wave inspection potential of defects in rail
The results of guided wave experiments carried out on test track and on 'live' rail are reported. Preferred propagation frequencies, modelling, roots of the dispersion relations for rail, and a wave displacement sample within a railhead are presented. Non-contact air-coupled and electromagnetic acoustic transducers (EMATs) are considered as receivers of rail sound energy. Experimental results from the use of air-coupled transducers to profile the rail radiation pattern are given. EMATs were used in a rail cutting experiment to simulate a transverse rail defect. Results of experiments are discussed and conclusions drawn.
