This article is based on the environmental impact report on the Auckland rapid transit scheme. This has the objective of providing a public passenger transport service which will make use of an electrified railway fully integrated and co-ordinated with road transport. It will involve a 30km rapid transit system and an underground loop line. The authors outline the proposals for the rail component including electrification, elimination of level crossings and a standardized service. Details of stations are given, which are designed for pleasantness and convenience, and include provisions for handicapped people. The route of the rail service is next discussed followed by brief details of the overhead power system. Three-car units each seating 150 passengers will operate at up to 120km/h two being operated in tandem during peak hours. After briefly describing the storage and servicing complex the authors discuss the construction of the underground section most of which will be excavated in unweathered sandstones and siltstones, which can be tunnelled by a header unit with a small traversing cutter or by a tunneling machine. 2.5 and 4 meter ventilation and emergency shafts will be incorporated. The 200,000 cubic metres of spoil are to be used in the Grafton Gully motorway construction. Environmental features of the system are discussed with particular reference to appearance and noise. Noise reduction is to be achieved by the use of long welded rails on rubber pads and heavy sleepers, by high quality alignment, the use of ballasted bridge deck designs and noise barriers. /TRRL/
