The dataset will include the raw data as measured by the instruments attached to the vehicles as well as the processed information derived from the raw data (vehicle dynamic response, track condition reports). The single trip data is used to report on operational issues (e.g. track defects and driving strategies). Aggregated trip data is used to report on and planning for track maintenance as well as the effectiveness of track maintenance. The data collected across the various rail networks in the long term will constitute a body of data that can be mined for information related to vehicle performance and the evolution of track condition under different environments.
