Germany Unveils First Self-Driving Train (techxplore.com) 60

Posted by BeauHD from the first-of-its-kind dept.
German rail operator Deutsche Bahn and industrial group Siemens on Monday unveiled the world's first automated, driverless train in the city of Hamburg, billing it as more punctual and energy efficient than traditional trains. TechExplore reports: Four such trains will join the northern city's S-Bahn rapid urban rail network and start carrying passengers from December, using the existing rail infrastructure. Other cities like Paris have driverless metros while airports often have automated monorail trains plying terminals, but those run on exclusive single tracks while the Hamburg train will be sharing tracks with other regular trains. The project, which Siemens and Deutsche Bahn called a "world first," is part of a 60 million euro ($70 million) modernization of Hamburg's rapid urban rail system. Although the train is controlled through digital technology and fully automated, a driver will still be present to supervise journeys whenever there are passengers on board, the companies said in a statement.

    • There have also been driverless trains at many airports for 40 years.

      According to TFA, what makes this train different is that it is the first driverless train that shares the track with trains operated by humans. I'm not sure why that is a newsworthy milestone.

They both operate on a preordained path and must be mindful of objects, and people, that are dynamic to their environment. An autonomous vehicle is basically a big ass robot.

        Actually, the rapid transit here in Vancouver could work, to a limited degree, with traIns that are being manually operated. All of the trains are equipped with manual controls, so certainly manual operation is possible. The system is designed with sensors in the rails, so that the trains can sense proximity to eachother and are capable of responding appropriately to that. If one train gets too close to another, the trailing one will slow down and/or stop.

      • No you didn't. You had driverless transit systems. They relied entirely on dedicated infrastructure to make them driverless. What you have here is literally just a driverless train, sharing tracks with other trains and pulling into normal stations. You didn't have anything like that until now.

        • You do realize its not the engineer that does most of the driving on regular tracks right? They control speed and brakes. Thats it. The majority of the operation of multiple trains on tracks are done remotely. At least in the US, one set of tracks operate in both directions. In order for two trains, traveling in opposite directions, to coexist, they must be timed to arrive at the same switching station close to the same time, so one train can be diverted to a parallel track long enough for the two to pass.

          • You do realize its not the engineer that does most of the driving on regular tracks right? They control speed and brakes.

      Because it's really not rocket science.
      There are sensors and triggers between the tracks and on the train. If it's underground, there's no people, so it's trivial.
      The only thing one might add for aboveground tracks, is the ability to stop if something is on the tracks.
      Which is basically one retroreflective sensor and a switch. Maybe with a slight rotation to follow curved tracks.

      As the summary points out, the innovation here is that these trains run on normal tracks with other manned trains, not special dedicated tracks.

      It's a big step up in complexity because rather than having a completely computer controlled system where the state of everything in it is known and stuff like signalling is purpose built for automation, it's more like a self driving car that operates on public roads.

      • A train operated by a human is in no way like driving a car. 90% of the trains operation is conducted off track at a control center. The operator controls speed and brakes. Thats it. The switching, akin to steering, is not done by the driver. You cannot compare it to autonomous driving.

      The "driver" has very little to no control already.

      All that's left is where he *could* make choices. Which can, mostly, be replaced with a bounded /dev/random. ;)

    • Because reducing the driver from the train isn't much of a cost savings. Already the ratio of passengers to drivers is easily 100:1 or more, a 99% reduction from a taxi where you'd be lucky to hit 1:1 (since the cab is driving around without any passenger some of the time). So, each passenger (or kg of cargo) on a train is already paying very little to the driver. Similarly, the cost pilot and crew is only 2% of a commercial flight, so going fully automated would save relatively little:

      Yes they have, on dedicated infrastructure. The "first" here is that this is a driverless train. Just a train. It uses normal tracks, normal stations, and shares that infrastructure with other rail vehicles.

      All other driverless systems to date have relied on dedicated infrastructure (like Rio Tinto's), fixed single use tracks laid out in a ring or two trains alternating (like those found at airports), or have a huge amount of dedicated smart platform infrastructure (like Paris Metro).

    • Also HSR trains are not fully automated. The only thing they do is adjust speed to suit specific segments of tracks. They are wholly reliant on the driver to stop, start, or to pull into stations.

We've made driverless transit systems since the 50s but they all rely on some combination of dedicated tracks, dedicated carriage, and dedicated stations loaded with sensors, or any combination thereof.

        E.g. the driverless train in Australia is travelling on a privately owned track. It doesn't need to stop or give way to other trains at any point.

    Since everyone is falling over themselves to point out that this isn't the first rather than actually RTFA, let me spell it out for everyone here:

    Existing driverless transit systems rely on some combination of dedicated tracks and smart infrastructure. This is a automatic train. It relies on neither. It uses normal tracks, normal stations, follows the standard signals, and shares a complex railway network with normal trains. That is what makes this unique and an order of magnitude harder problem to solve than any of those monorails you've travelled on when changing airport terminals.

    Give them some credit where it's due.

    That said, there's still a safety driver on board, so not fully driverless yet. But my guess is he'll be watching youtube videos rather than doing anything meaningful.

      • No. BART is a fixed single purpose metro network, point to point, doesn't share any tracks with non-BART vehicles, and the last time they attempted a truly driverless system a carriage launched itself off the end of the track. Additionally the BART network's driver automation relies heavily on the network itself, and the only line really capable of full automation is a guideway transit line like the Paris Metro 14 and doesn't even connect to any other tracks in the BART network.
