Currently, rail infrastructure managers have dedicated vehicles to carry out track measurement. These vehicles are, however, expensive to procure and run as they need specially trained crews to operate them.

Consequently, the UK only has 6 such measurement vehicles and the mainline network is only inspected on a 4-6 weekly cycle (less regularly for other services). This work demonstrates the application of an inexpensive inertial measurement unit (IMU), installed on an in-service passenger train, and using novel algorithms, to provide continuous monitoring of the track and its degradation. Two IMUs were fitted, one on the bogie and one in the cab. Inertial data from the bogie mounted IMU was collected and processed to provide vertical and lateral displacement profiles of sections of track from multiple passes of a rail vehicle. A modified Kalman filter was used to produce the associated dataset profiles to within 0.2 mm location accuracy.

N2 - Efficacy in railway track maintenance is not only critical for safe operation, but by reducing delays and increasing capacity, can result in economic benefits for rail operators. Currently, rail infrastructure managers have dedicated vehicles to carry out track measurement. These vehicles are, however, expensive to procure and run as they need specially trained crews to operate them. Furthermore, they require uninterrupted access to the track, and so are difficult to schedule around other services.

A modified Kalman filter was used to produce the associated dataset profiles to within 0.2 mm location accuracy.
