Abstract
A method of constructing a rail track in which a concrete track slab is produced and rail track anchor members are inserted in the track slab by an inserter system mobile along the route of the rail track includes the following steps: using a machine for continuously pouring concrete to produce two concrete walls laterally delimiting the edges of the track slab to be poured; pouring the concrete track slab between the walls; and using the inserter system to insert anchor members in the freshly poured track slab, the tie plate inserter system being adjusted accurately by a measuring station, topographical survey points, a measuring system, and reflectors carried by the inserter system.
