Railway brake systems are mainly of the air brake type which relies on pressurized air to push brake shoes or pads against wheel treads or brake disks.

In Sweden a new word - TГҐgskryt (вЂtrain bragвЂ™) - has entered the lexicon to describe when people encourage others to take the train.Train companies in Spain, France and Germany are already ordering high-speed and cross-border trains to meet anticipated demand. For instance, taking the train from Zurich to Milan, a 217km trip, instead of flying saves around 103kg of CO2 emissions per passenger, according to a Deutsche Welle analysis.Passenger rail numbers in Europe were steadily growing for years before national lockdown measures in early 2020. Rail journeys can reduce travellersвЂ™ emissions. More and more people are looking to rail as a safe and environmentally friendly way to travel.

This makes emergency braking difficult.His team is looking at ways to improve another type of braking technology, one that uses electronics to make sure that train carriages reliably haveВ a consistent stopping distance, give permanent feedback, and are longer-lasting than the types of brakes currently available.Replacing air brakes with radio-controlled, electro-mechanical brakes brings a lot of advantages, says Ertl. In combination with difficult friction conditions this means while the carriages at the front may have a high deceleration rate, the last carriage is hardly braking at all. And since the air moves through each carriage in sequence the brakes are activated simultaneously but may react with some latency.

If a train needs to brake suddenly, other trains using the line need to know so they can avoid collisions. Image credit - Knorr-BremseBut making sure more trains can travel on the tracks requires more than better brakes. This includes testing the brakes in their Munich site in a 15-metre high, 760 tonne test rig called ATLAS that can reach speeds up to 350 km/h.PIVOT2's project is currently testing its new pneumatic braking technology in a 15-metre high, 760 tonne test rig called ATLAS that can reach speeds up to 350 km/h. Early tests have shown these prototypes to be 16% lighter, reduce the braking distance by 40% and reduce wear by 55% compared to conventional brake pads on the market.At the moment, the project is further testing the new pneumatic braking technology. The project is also looking at new additional systems that can offer better braking performance in wet or slippery conditions.The project has designed a prototype pneumatic brake whose brake pads use lighter materials, different surface patterns to improve its grip, and has fewer components. This data can then, for example, be shared in advance with depots so they can better plan when to bring the train in for maintenance.While controlling brakes using an air pipe works well for air brakes, controlling brakes using radio signals works best for modern electro-mechanical pneumatic brakes.

Instead of travelling along fixed lengths on a track, trains can communicate with each other and calculate what distance they need to keep away from each other.вЂItвЂ™s no longer based just on the вЂњworst-caseвЂќ type of train,вЂ™ he said. ThatвЂ™s why train companies are looking at using вЂmoving blocksвЂ™ to separate trains. This forces trains with better braking to travel according to the worst-braking train on the track.вЂIn traditional signalling, which is based on fixed blocks, the block structure is hard coded into the railway,вЂ™ he explained.This can be a waste of space, he says. According to one estimate a block can range from 500 metres to six kilometres, depending on the type of train and its speed. Lighter, shorter passenger trains need less braking space, but still need to travel along these same fixed blocks.

The current phase, X2RAIL-5, is using computer models to analyse both the cybersecurity of the equipment and see how it might behave in the real world. It can potentially reduce costs since less trackside train-detection equipment is needed, and itвЂ™s more reliable since the train is constantly sending updates about its position.вЂ‹вЂ‹Better train monitoring, he says, will be important for the nascent European Train Control System (ETCS), a common set of rail monitoring, signalling and safety systems вЂ“ both trackside and on the train вЂ“ that is slowly being applied throughout Europe.The previous phases of the X2RAIL project focused on designing ETCS satellite and radio technology to be installed on the trains. This satellite and radio-based information is faster to transmit and is more efficient than train monitoring equipment installed directly on the tracks, says Chadwick.Radio and satellite technology can also help if a carriage detaches from a train since equipment on both the train and the carriage can send an alert, whereas carriage-counting equipment installed on the track will only detect the loss when the train reaches it.вЂWe have to reduce the headways (distance) between the trains without compromising safety.вЂ™ Martin Ertl, Knorr-Bremse, GermanyUsing satellite and radio technology on trains has benefits beyond increasing capacity on railway lines, says Chadwick.
