Adopt, adapt, and improve: Assessment of a new driver display in rail

Abstract

This project evaluated the impact of a new enhanced information display intended as a cognitive aid on the operating performance of Locomotive Engineers (i.e. Train Drivers) within a large New Zealand freight rail network. The display previewed the upcoming route and presented information capable of optimising the performance of the locomotive. It did not exert any direct influence over the train and therefore did not take any decision-making capacity away from the driver. The addition of this technology represented a step-change for the organisation and a considerable investment for furthering safety and performance by improving the situation awareness of train drivers. Improving situation awareness is likely to lead to improved decision-making and hence performance and safety (Endsley, 1999) However, given the impact on ways of working for the train driver, and on the development of the organisation, acquiring insight into the cognitive, organisational and/or physical ergonomics impact of the technology was critical and attracted the need for a human factors assessment
