Ottobahn develops autonomous elevated railway system
The Munich startup ottobahn has set itself the goal of developing an individual elevated railway system that combines the advantages of public transport with those of a flexible means of transport. The so-called ottobahn, which operates autonomously and electrically, is intended to offer high transport capacities and be completely decoupled from current traffic. The tracks should also seamlessly integrate into the cityscape, creating additional space for pedestrians and green areas. In this concept, there are no stations, only individual stops, and the pods rotate according to the swarm principle, that's the ideal. The young company, founded in 2019, relies on lightweight and yet very robust materials. This is intended to ensure that the classically rail-guided system also achieves a high infrastructure durability of 100 years, as promised. The patented passive switch system manages without moving parts and minimizes maintenance effort, according to the announcement.
Fully Autonomous and Rapidly Fast Pods
The "tracks," derived from roller coaster construction, run at a height of five to ten meters on common concrete pillars. Using an integrated lifting module, borrowed from the elevator industry, the cabins could be practically lowered to the ground anywhere within seconds, the provider advertises. Each cabin will be equipped with a series of precise sensors that can detect every person and obstacle in the entry area.
This ensures a safe lowering of the cabin to the ground. Through fleet management, the traffic flow in the entire ottobahn transportation network will be optimized with AI support. The fully autonomous pods determine their route independently and bring passengers to their destination without intermediate stops, the developers further promise. On highly frequented sections, parallel tracks will allow seamless integration of boarding and alighting into the ongoing traffic.
Low Energy Consumption, Modular Cabins, Also for Cargo
The chassis of the cabins is based on the proven and energy-efficient combination of wheel and rail. With an electric drive power of 2.4 kW, the expected energy demand is 1.8 kWh / 100 km in the 400-volt AC system, equivalent to a consumption of 0.5 l/100 km in a car. For energy supply, photovoltaic modules along the route will be used. The maximum theoretical speed is set at 250 km/h, which would also enable long-distance travel. In urban reality, speeds of about 60 km/h are targeted.
According to the manufacturer, the "bionically inspired" exterior shape of the cabin will achieve an aerodynamic drag coefficient of less than 0.2. By coupling the cabins into convoys, they aim to reduce air resistance even further. The cabins are modularly constructed, allowing the interior of each cabin to be individually designed, also for cargo applications or comfortable single rides.
Outdoor Test Track to Begin Operations Soon
ottobahn GmbH was founded in July 2019 in Munich, named after Otto I, Duke of Bavaria (1120-1183). It is privately financed, and the team predominantly consists of software developers and mechanical engineers. Since February 2020, a first test track has been operational indoors. GEN II of the chassis and cabin has been completed, and groundbreaking for an outdoor test track will take place shortly and will be realized in 2022. A total investment of five million euros is planned until 2023. It is conceivable that the test track could be extended in Taufkirchen up to Carl-Preis-Platz in Munich-Haidhausen, as ottobahn CEO Marc Schindler explained to the FAZ. He sees a start in 2024 as ideal. This is ambitious for a distance of around 15 kilometers.
