There is disclosed a train positioner for sequentially advancing a string of railroad cars to a rotary car dumper in a step-by-step and a car-by-car sequence. Each of the cars has rotatable couplings permitting the rotation of each car about a longitudinal axis. The rotary car dumper is adapted to invert a railroad car about that axis. Two car-pushing members are provided which are adapted to sequentially engage a car and advance the car toward the dumper. A drive arrangement is provided which is adapted to drive at least one of the pushing members forwardly toward the dumper a distance corresponding to about the length of a car while that pushing member is engaged with a car while retracting at least one other member rearwardly away from the dumper a distance corresponding to about the length of the car while being disengaged from a car.
