A concreting train consists of a plurality of wagons supporting a mixer, a multiple conveyor arrangement and separate containers for cement and aggregate. A container for cement has at least one integrated conveyor worm. All container wagons are provided with inclined conveyor belts which extend below the containers and overlap one another. On separate pathes aggregate and cement are supplied into a housing of the mixer wagon. The housing is supported on a weighing frame in order to additively weigh the mixing components. The housing contains a mixing shaft operatively connected with a drive motor. The housing is mounted for reciprocating movement along an inclined angled track in order to lift the housing on a higher level for discharging the concrete into a hopper of a concrete pump. The concreting train is adopted to be used in narrow tunnels in order to provide a multiplicity of small batches of high quality concrete in very short periods of time at the face, whereby quality and consistence can be quickly varied.
