More than 2 out of every 5 miles of America's urban interstates are congested. Traffic delays cost the U.S. $160 billion in wasted fuel and time. Most american cities lack commuter rail or subway systems.
Building new light rail systems is expensive and time consuming. But what about the existing rail infrastructure most cities already have?
Under-utilized freight tracks
Most cities are criss-crossed with train tracks used for freight trains. If these tracks could be used for passenger traffic, they could provide high speed rail service that could bypass congested areas of the city without adding any additional infrastructure.
A vehicle that could drive on both roads and rails would be able to connect residential and business areas to rail corridors and combine the localized service of buses with the speed of trains.
road to rail
The Railbus has train wheels mounted on the inside of it's bus tires. Using concrete ramps located in train yards or road intersections it can drive smoothly between train tracks and regular roads.
