1,064,787. Railway vehicles; hopper wagons; wagon doors; cars continuous forming trains; undercarriages.DEVENCO Inc. Dec. 11, 1963 [Dec. 28, 1962], No. 48849/63. Heading B7L. [Also in Division F2] A railway train comprises power packages 14, Fig. 1, each in the form of two locomotives 15 permanently pivoted through draw-bars 17 to a fuel car 16 between them, the packages 14 being dispersed between freight vehicles 10 each comprising a plurality of compartments 11 permanently articulated to each other through draw-bars 12, and end control cars 20. The control cars, packages and freight vehicles are joined together by conventional couplers 13, 18 and 21. The power packages contain electrical apparatus remotely controllable from either end control car 20 as described with reference to Fig. 8 (not shown), and the packages supply the motive power and electric heating and control the brake and door apparatus of the train. Referring to Fig. 2, each compartment 11 of a freight vehicle 10 comprises a body 22 having a longitudinal hollow centre sill 23 rigid at each end with a body bolster 41. Each body bolster 41 is connected by a king-pin 42 and centre bearing to the bolster 43 of a four-wheel bogie truck comprising side frames 46 connected at their ends by wheel axles 50, the bolsters 43 being supported from their side frames 46 by " Belleville " springs 47. The body bolsters 43 at the outer ends of the end compartments of the vehicle 10 are pivotally connected by the pins 42 to conventional separable couplers 13, Fig 3 (not shown), whereas the body bolsters 4y of adjacent compartments are permanentl3 articulated by the pins 42 to the draw-bars 12. The hollow centre sill 23 serves as a highpressure air manifold 64, Fig. 9 (not shown), for the braking system. Each compartment 22, Fig. 4 (not shown), has a pair of horizontally extending drop-doors 25, 26 pivoted at 27, 28 to the sill and latchable at 31 to the compartment bottom walls 34. The latches are opened by pneumatic cylinders (not shown) and closed by pneumatic cylinders 35, 36 connected to the doors and the sill. The brake apparatus for each bogie comprises shoes 54, Fig. 5 (not shown), carried by beams 52, 53 and urged away from the wheels 51 by springs 56 housed in the side frames 46. Each beams is connected by a member 62, passing through a slot in the side wall of the bolster 43, with a piston 59 in a cylinder 60 carried by the bolster. Air is supplied from a reservoir 65, Fig. 9 (not shown), provided for each compartment 11 via a triple valve 66 to the cylinders 60, the valve 66 being connected to the usual train pipe 63. The reservoir is also connected through a check valve 69 with a high-pressure manifold 64 for quickly restoring the reservoir pressure.
