Train Data Processor output
The Train Data Processor (TDP) takes the output from on train data recorders (similar to the "black box" on an aeroplane), automatically situates the train (since location is not recorded) and compares in service train speed distance traces (the "thin squiggly" traces below) to optimal best practice speed distance traces (the smooth blue trace, above the "squiggly traces", below).

Train Data Processor uses and history
Traditionally data recorders have been used for maintenance and safety purposes only. Cogitare identified the potential to use these outputs to increase the efficiency of operations:

• Better understand the interaction between train drivers and infrastructure;
• Identify where and how signage can be improved to minimise run-times and run-time variability;
• Target driver training to where it will reap the greatest benefits and a tool with which to monitor and train drivers.

Cogitare then produced a world first by developing the software to automate the conversion of the data into a readily usable format which compares actual to best-practice. The software uses intelligent sequential distance comparisons to automatically locate trains and interfaces with Automated Single-train-simulator Database outputs to allow the comparison between best-practice and actual in service driving styles.

London Underground and Cogitare are now looking at how the software could be implemented within driver training initiatives and the software is due to be further developed to enhance functionality.
