The Laval track consists of two longitudinal rows of reinforced concrete blocks, one under each rail. The blocks measure 1.3 m long 0.7 m wide, and 0.16 m deep. Each block weighs about 750 lb. Between successive blocks there is a space of 0.2 m in which steel tie-bars are fixed to the rails for retaining the correct gauge and the 1 in 20 cant of each rail. Details of track design and installation are examined.
