The Jean River near Wabush, Labrador is crossed by two railways and an access road by twin 6m diameter culverts . They are heavily strutted inside their barrels to counteract some significant shape deformation, and are deemed not suitable to sustain the increased volume of rail traffic serving the development of the Bloom Lake mines. The owner requested the design and construction of a replacement scheme for an additional design life of 20 years with a time sensitive schedule for completion of the work during the 2013 construction season. This VE concept for the design of live load relief spans …

A special track system used to divert a train to other directions or other tracks is generally called ‘railway turnout’. A traditional turnout system includes rails, switches, crossings (special track components), steel plates, fasteners, screw spikes, timber bearers, ballast and formation. The wheel rail contact over the crossing transfer zone has a dip-like shape and can often cause detrimental impact loads on the railway track and its components. The large impact also emits disturbing noises (either impact or ground-borne noise) to railway neighbors. In a brown-field railway track where an existing aged infrastructure requires renewal or maintenance, some physical constraints …
