    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3939 KB)

    Monitoring of railway objects is relatively new. Maintenance organizations have to adapt to the use of monitoring systems. Various examples prove that condition monitoring can: reduce the number of failures and thus improve the availability and; facilitate condition based maintenance. The introduction of point monitoring in three different organizations is described. The adaption of organization t... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (4323 KB)

    Track recording vehicle equipment has been miniaturised to such an extent that it can be mounted on an in-service vehicle for monitoring track geometry. An alternative approach is to mount a few robust sensors such as accelerometers and rate gyroscopes onto the bogie and axleboxes of an in-service vehicle. The track geometry information that can be obtained from these sensors is incomplete; in par... View full abstract»

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (3033 KB)

    The dynamic response of a railway vehicle is dependent upon the interaction between the wheel and rail. Currently these key components are monitored for wear and condition off-line and separately. However, it is the combined nonlinear interaction that really affects the dynamics. This paper presents the initial Rail Research UK (RRUK) sponsored feasibility study into estimating the wheel-rail prof... View full abstract»

  • The Effects of Tilting Trains on the Track Superstructure

    Publication Year: 2006, Page(s):38 - 43
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2272 KB)

    The tilting technology, in comparison with the conventional trains, assures in the curved sections of the track alignment and for the same running speed, a smaller value of noncompensated centrifugal force on the car-body level. As a result, using this technology, the running speeds in curves can be increased while still keeping, on the car-body level, the same value of the non-compensated lateral... View full abstract»

  • Event Monitoring Comes of Age: `Predict and Prevent' as Well as `Find and Fix'

    Publication Year: 2006, Page(s):44 - 47
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2885 KB)

    Remote monitoring of trackside railway assets has until recently had a deservedly bad reputation. Early systems generated large quantities of unreliable data, and although some simple event monitoring was useful in finding and fixing faults, busy maintainers did not trust the veracity of the data, and in any event did not have the time to collect it nor to analyse it in order to help prevent train...

    This paper describes the installation by Metronet Rail of a remote monitoring and data logging system supplied by Transmitton Ltd on the central line. It details what data was available prior to the start of the system's introduction, describes its limitations and the difficulties involved with identifying the cause of "no fault found" failures. It outlines how the remote monitoring system has ena... View full abstract»

    The Regina trains, manufactured by Bombardier Transportation, contain software and hardware to generate as well condition data as event data that can be used to monitor the condition of the trains. In this paper we present the necessary equations for abnormality detection of both event data and condition counters in a general setting. The use of the equations is illustrated on authentic data from ... View full abstract»

    Transmission Dynamics of Northern Power Transmission Research Laboratories jointly with Bombardier Transportation have developed a practical and robust method of in-service measurement of railway axle stresses. The ultra miniature data logging system was specified and installed on a routine service train and was in continuous operation on a wheelset for more than one year. The acquired data provid...

  • Acoustic Monitoring of Rail-Head Roughness for Targeted Grinding and Noise Modelling

    Publication Year: 2006, Page(s):61 - 62
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1753 KB)

    Railway rolling noise is a function of the combined roughness at the interface between the wheel and the rail. If wheels are comparatively smooth, the combined roughness is dominated by the rail-head roughness. It is therefore possible to monitor the level of rail-head roughness, and especially short-wavelength corrugation, by measuring the rolling noise with a microphone mounted on the underside ...

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (4288 KB)

    Low adhesion in wheel-rail contact causes huge problems for scheduling and safety of railway networks. Braking and guidance forces have the same force generation mechanism, via the creep forces at the wheel-rail contact. This paper demonstrates the application of a Kalman filter to estimate the adhesion condition on the rails. The key aspect of this approach is that estimation is carried out on-li...
