NON-STOP ON THE TYNESIDE EXPRESS

This article is concerned with the construction of the first stage of the Tyneside metro. Monorails and minitrains were considered but rejected as offering no real advantages, and London style heavy tube trains discarded in favour of 27M long articulated cars in a light rapid transit system. A 75 percent government grant has been approved. The system is being fully integrated with other forms of transport, and A study has shown the system as giving an eleven percent return over an all-bus system. The author discusses the form of stations followed by an account of the construction of the first stage with particular reference to the problems encountered. Boulders prevented the use of a full-face tunneling machine and shields and roads headers are being used from both ends. Methods will be adjusted to suit ground conditions, and particular care is being taken to ensure the stability of overhead buildings. The methods include the specification of compressed air in some areas and, the use of small explosive charges to remove siltstone. Tolerance in line, grade and circularity is only 30mm overall. The gateshead side of the river is riddled with old mine shafts, and requires special methods. These include drilling and grouting from above and the pneumatic stowing of pfa/cement and stone/cement grout. /TRRL/
