PACT PROVES ITS WORTH IN SPECIAL APPLICATIONS

The eight years since the first experimental length of paved concrete trackbed (PACT) was laid in Britain have seen growing acceptance of this design if maintenance-free track is desirable such as in tunnels and viaducts where mechanized maintenance is difficult. No substantial length of PACT has yet been laid, although first cost is now only one third greater than for conventional track. One obstacle (except on entirely new lines) is the lengthy possessions required for the sophisticated slip-form paving process. PACT is being tested on the Spanish National Railways and New Zealand Railways, as well as on British Railways which will use it in the 7-km tunnel under the Severn estuary.
