On track vehicle speeds may need to be restricted to 40mph in city centres to cope with the necessarily tight turns. Once out of the centre, speeds of 60mph to 80mph will be the norm, with up to perhaps 150mph on main trunk routes. Door-to-door commuter journeys of 20 miles will generally take about 20 minutes. Intercity journeys will be faster, and usually very much faster, than any existing means for routes up 400 miles, with air travel getting even at around 500 miles. The benefit of the short journey times is enhanced by the fact that journeys can start on demand, not when scheduled by a transport operator.

To reduce aerodynamic drag on the higher speed sections vehicle speeds will be adjusted to bunch vehicles into short trains where appropriate. Suspension drag, the equivalent of rolling resistance, will be very low, making overcoming aerodynamic drag by far the main power absorber.

To save the cost of equipping all cars with sufficiently powerful propulsion to achieve the higher speeds, these could be made possible only once ad-hoc trains are formed, when all vehicles forming the train contribute to overcoming the drag felt by the leading car. The highest speeds will be available only on special trunk routes.

BiWay Journey Time Comparisons

Door-to-door times for journeys up to about 500 miles will be shorter, and in most cases, very much shorter, than any current system provides. Travel will also be more comfortable and available when wanted, not when it suits the transport company but longer journeys may require an occasional 5 to 10 minute comfort stop.
