The Oakland Airport Connector: Bringing cable cars back to the Bay Area! (maybe)

Cable Car at Doha International Airport (planned)Despite all the controversy, the BART Oakland Airport Connector project in the San Francisco Bay Area is an exciting project. This is because BART, the agency in charge of building the project, is using an open bidding process that allows for anything from maglev trains to cable cars to be used. So, does this mean that BART, ‘the most advanced system in the world’ (at the time it was built) might actually build a cable car? Yep! And this website thinks that’s a good thing. DDC – Doppelmayr Cable Cars, a wholly owned subsidiary of the Doppelmayr Garaventa Group (a company that primarily makes chairlifts and gondolas) makes just the right kind of train for this project.

That’s because the cables are fixed to the cars. So there is no wear and tear on the cable, or jerky motion, when the cable car needs to stop and go. Because the technology is so simple it’s quick and easy to construct. It is also very reliable and it is affordable too.

One of the biggest advantages of this technology is that the train cars are so light weight because the engine is located at the station rather than in the car itself. This means that the guideway doesn’t require as much concrete reinforcement and is much cheaper to build. The light weight also reduces wear and tear on the cars and the tracks which reduces maintenance costs.

Because the length of the railway needs to be over three miles, two trains would probably be best for this project in order to decrease headway times (the time interval between trains). This doesn’t mean that two tracks need to be built though – just one track would suffice, except for a short distance to allow the trains to pass halfway between the airport and the Coliseum BART Station. (Although two tracks could be built to make the system even more reliable).

Additionally, because only one car would pull into either terminus station at one time, it is possible to build very simple, low cost stations. Furthermore, passengers can board and exit the train from both sides, which reduces dwell time (how long the station spends at a station) and lowers headway time.
