Silver machine rolls down the track to new efficiency record
Students from Dalarna University, Sweden, have won a competition for creating efficient rail-based transport, claiming world record in the process. Team Eximus 1 was competing in Delsbo Electric, where teams must design and build a battery-operated railway vehicle that uses as little energy as possible.
Delsbo Electric is open to college and university students. It was inspired by the Shell Eco-marathon, with the concept translated for rail-based rather than road-based travel. The track along which the vehicles must travel is 3.36-km (2.09-mi) long and stretches from Fredriksfors to Delsbo in Sweden. Its relief rises and drops by about 3 m (9.8 ft) along its course.
Vehicles must carry between one and six passengers weighing a minimum average of 50 kg (110 lb) each. Vehicle efficiency is measured on a per person basis, meaning vehicles carrying six passengers are not at a disadvantage. They must also be equipped with brakes and be designed not to derail.
Team Eximus 1 prepared for the contest over the course of 15 weeks. The team of four studied previous designs entered into the competition and even went so far as to design and manufacture the wheels for their vehicle.

They could have jogged or biked faster and used less electricity. It's a nice class project, but not exactly a breakthrough technology with much practical application.
