The Transient Railway Aerodynamics Investigation Rig

The Transient Railway Aerodynamics Investigation Rig(TRAIR) is a unique test facility that is able to test model-scale trains at speeds up to 315 km/h. It is unique in its ability to measure transient aerodynamic effects that occur when trains pass in the open or travel through tunnels. These effects cannot be simulated by conventional wind tunnels.

    TrackMaster®

    TrackMaster is a tool that helps monitor, plan and optimise track maintenance schedules to ensure that best use is made of track maintenance plant and manpower.

    The software enables the user to monitor the condition of track using a number of visualisation tools and then optimise the use of track maintenance machines, targeting them where they will be most effective and/or are required in order to maintain track quality.

    VAMPIRE®

    VAMPIRE® is DeltaRail's world class vehicle dynamics software with over 100 licences in use world wide. Based on the fundamental research carried out by British Rail, this product has been continually developed over the last 30+ years and is now in it's fifth generation as VAMPIRE® Pro.

    WSPER®

    The Wheel Slide Protection Evaluation Rig is a unique facility that enables a train's anti-lock braking system (WSP) to be thoroughly tested and evaluated under realistic simulated low adhesion. In essence, the rig "fools" the WSP electronics into thinking it is on-board a real train which is braking in slippery conditions. The decisions that the WSP system then makes are monitored and fed into the real time model to give a prediction of stopping performance, wheel damage and the amount of air consumed during the stop:

    Using the facility, manufacturers of WSP systems can test, refine and re-test their WSP electronics to improve its performance. So successful has the rig been that virtually all new passenger rolling stock in the UK is equipped with a WSPER optimised WSP system.

    VERSE

    VERSE is a non-intrusive means of establishing the stress free temperature of rails. The system, developed by DeltaRail, features:

  • non-destructive measurement of stress free temperature
  • it is relatively quick and easy to use
  • the system is computer guided for error free measurement
  • rails are only cut when re-stressing is needed
  • it is accurate with a mean error ± 0.2 °C
  • it can be used down to 700 mR curve

    The system is marketed and sold through our partner company VORTOK International world-wide who can be contacted by email at sales@vortok.co.uk or by phone on +44 (0) 1752 700601.

    Driver Skid-Pan Training

    Many areas of the country suffer from low levels of wheel/rail friction at various times of year, typically in late autumn or early on spring mornings. The conditions are the railway equivalent to black ice on the roads and it is important for drivers to both appreciate that such conditions can occur and to learn to react appropriately.

    DeltaRail has two "tried and tested" methods for simulating low adhesion which have been used extensively in recent to train railway drivers (particularly new drivers) in the techniques to employ in slippery conditions:

  • The detergent spray method - a mix of water and detergent is sprayed in front of the leading wheelset to generate low wheel/rail adhesion.
  • The paper tape method - paper tape is rolled onto the railhead and then conditioned such that it turns into very realistic leaf film which, when moistened appropriately from on-board spray equipment, produces worst-case operating conditions.

    Laying Paper tape for Skid Pan Training

    The on-train spray equipment used has been developed over a number of years and the current set-up is compact and easy to install / remove. Bespoke paper tape laying trolleys (as shown above) have also been developed over a number of years and facilitate the rapid and reliable deployment and removal of paper tape to / from the rail head.

    If you would like further information on the artificial generation of low adhesion conditions for driver training or other purposes, such as post-incident testing of train braking systems, facility, please contact Sam Richardson by email at sam.richardson@deltarail.com or by phone on +44 (0) 870 190 1568.
