RAIL ALTERNATIVE

This article describes progress on the development of a light rail system for Dallas, TX, USA. The design was completed in 1990, and most of the line will be overground. 21 stations are being built, of which the larger will have park-and-ride facilities and bus interchanges. The most demanding stretch of the line is an 8.8km long tunnel, with one underground station. The tunnel will pass through soft but stable Austin chalk, which will be ideal for drilling. About 90% of the tunnel will be sprayed with polyfibre reinforced concrete, and the remainder, which will form the station platforms, will have a reinforced concrete lining cast in situ. There are also plans for a possible second underground station, which could be built later; the tunnels have been widened at its location. Outside the tunnels, the construction work is fairly straightforward, with tracks running at ground level, and supported on concrete foundations. A commuter link is also planned between Dallas and Fort Worth, with links to the international airport between them.
