High speed rail

► Population densities are far lower in the US than in countries with high speed rail networks. ► Most US office space is decentralised, not in down-towns. ► Most business travel is suburb-to-suburb, not centre-to-centre, and requires a car. ► Medium-distance travel, most suitable for high speed trains, is mainly by car, not plane. ► High-speed rail works best as part of a strategy embracing economic and industrial development.
