Improved braking through controlled water addition

通过控制加水改善制动多年来，英国铁路行业一直在努力应对低附着力的影响。这个问题在秋季最为严重，因为赛道边的落叶会导致非常滑的情况--即所谓的“落叶问题”。每年，英国铁路行业花费超过5000万GB试图解决这一问题。我们发现，在有大雨的日子里，这个问题根本不会发生，即使是在秋天。我们的解决方案只是在检测到滑轨时，从火车向铁轨喷洒少量水，从而在铁轨上制造“雨天”条件。我们的想法在一列测试列车上被证明是有效的。该项目旨在扩大这项工作，以证明在客运列车上的好处。

Improved braking through controlled water addition For many years the UK rail industry has struggled to manage the effects of low adhesion. The problem is most severe in Autumn when track-side leaf fall can contribute to very slippery condition - the so called problem of "leaves on the line". Annually, the UK rail industry spends over £50 million trying to deal with the problem. We discovered that the issue doesn't occur at all on days with heavy rain, even during Autumn. Our solution simply creates "rainy day" conditions on the track by spraying a small amount of water from the train to the track when a slippy rail is detected. Our idea has been shown to work well on a test train. This project aims to extend the work to prove the benefits on a passenger service train.
