STEEL RAILWAY BRIDGES: RECENT DEVELOPMENTS . DEVELOPMENTS IN STRUCTURAL ENGINEERING. PROCEEDINGS OF THE FORTH RAIL BRIDGE CENTENARY CONFERENCE, HERIOT-WATT UNIVERSITY, ENDINBURGH, SCOTLAND, AUGUST 21-23, 1990. VOLUMES 1 AND 2

The paper describes steel rail bridges of short and medium span. Developments arising from availability of better steels, erection by large craneage and publication of new codes are covered. Evolvement of steel rail bridges since the 1950's is outlined. The legacy of nineteenth century bridges having trough girders with track directly fixed is shown to influence modern bridges using ballasted track, necessitating floors of minimal depth. Development is described of the trapezoidal box girder type with steel floor. A 1989 redesign of the box girder range is described for single or double tracks with skews up to 55 deg and maximum span of 39 m. Developments to improve maintenance include better access inside permanently ventilated boxes and movement bearings. Plans for future development allow for factors such as the European loading, deformation criteria under highspeed traffic and a wider structure gauge. The paper includes some examples of recent bridges. These include the box girder Atlantic Road Bridge at Brixton Station in North London, the Lingard Lane Bridge (a Warren truss example), and two composite bridges, the integral rail and road bridge at Ebbw Vale, and the viaduct for London Docklands Light railway.
