Their should be zero tolerance towards railway derailments. Uncontrolled excessive damage to infrastructure by a minority of vehicles outside reference conditions impedes commercial success and the ability to improve railway performance. Very little investment is being made to prevent derailments, apart from in signalling. UMS (Unattended measurement systems) represent a viable alternative to dedicated, measuring vehicles as the measurement results are comparable. Advances in electronics, component reliability and wireless technology make it possible for UMS to operate autonomously on standard vehicles in normal revenue service. Data is automatically collected and transferred to a central data storage where it is processed and key information is reported to staff. UMS make it possible to dramatically increase the frequency of inspection, while significantly reducing operating costs. Data is available as often as the host vehicle runs along the track. Continuous operation over dedicated track sections provides managers and engineers with current information for making decisions and taking appropriate action. UMS provides warnings of sudden changes in the infrastructure, allows the rate of deterioration at any location to be monitored and predicted. and enables the quality of track works to be determined quickly. Safety can be addressed weekly rather than quarterly. Data localisation, validation, and segmentation are still an issue for UMS, but it will become an embedded monitoring system in rolling stock. Some railways are now considering equipping new rolling stock with UMS.
