About us


Unrivalled experience

RailMeasurement‘s specialty is the development and production of robust and reliable equipment for the accurate measurement of rail transverse and longitudinal profiles.
Our instruments are used by clients whom carry out routine rail inspections, contractors whom need to verify quality of mobile rail treatment and acousticians who undertake research on wheel/rail noise.

Thorough validation

All of our products have been the subject of thorough validation not only by ourselves but also wherever possible, independently by experts working in the area.

Robust and reliable

We are keenly aware of our responsibility to support our clients with equipment of the highest standard in accuracy, reliability, ease of use and independent verification. Some of the original CATs that were supplied in the late 1990s and early 2000s to railway administrations and rail grinding companies are still in use. Many of the RCA’s supplied to our clients in the early 2000’s have seen nearly 2 decades of use with minimal maintenance and still measure to microns.

He has undertaken consultancy in several areas of vehicle/track interaction, including rail corrugation, rail defects such as RCF and studs, wheel/rail noise and rail reprofiling. His work, including review papers on rail corrugation is widely referenced in the field.
