    Improved train safety through improved locomotive braking performance : SRDC final report QUT019
    (Sugar Research Institute, 2009) McKenzie, NJ; Koppen, DE; McCallum, C; Kent, GA; Plaza, F
    The safe operation of the cane railway, in the same way as for mainline railways, is gaining greater attention. One important aspect of safe operation is the ability to stop a train in an acceptable distance (or time). Previous work has measured quite variable braking performance (and hence stopping distance) in an extensive series of tests with different locomotives on different track sections in different mill areas. It was found that the locomotive driver was the most variable factor associated with braking performance. When the driver factor was eliminated through the application of a fixed braking pressure, very consistent braking performance could be achieved. It was concluded that it was the driver’s ability to detect wheel slide and their action to reduce slide that caused the variability in braking performance. It was hypothesised that an anti-lock braking system (ABS), where the driver has little influence on the braking performance, could deliver better average braking performance and hence reduced, or at least more consistent, stopping distances.
