Fastenings operated mechanically from a distance. -For simultaneously locking all the doors of the carriages of a railway train, two parallel tubes B, B' are provided on each side of the carriages, each pair being connected by a number of levers C situated over each door, the levers being pivoted at d to brackets D and fixed to the carriage and carrying a projection or catch F. The rods B, B1 are moved in mutually opposite directions by an arrangement, placed in the guard's van or locomotive cab, comprising a lever K moving over a quadrant L and retained at the ends by a spring catch k engaging teeth in the quadrant, the pivot of the lever being square or suitably shaped so as to move the corresponding lever C on the outside. A projection k' on the spring catch adapted to engage with the pin k2 in hole k1 is provided, whereby one lever can be put out o) action when another happens to be on the train The ends of the tubes are provided between the carriages with spring buffers G, G'. Rods may be employed in lieu of tubes, in which case they are provided with tubular ends to receive the stem and spring of the buffer.
