Hyperloop

The Hyperloop is cutting-edge mass transit engineering that links much of the Eastern Seaboard together. Travelling from Gotham to New York to Metropolis takes less than fifteen minutes; in under an hour one can travel as far south as Washington DC. The trains run on modified repulsor maglev circuits designed by Stark Industries, while Wayne Engineering handled the infrastructure. The fare is kept affordable enough for blue collar workers to use the train reliably.
