Abstract
1419565 Portable railway track sleepers SWEDISH RAIL SYSTEM AB 20 Feb 1973 [29 Feb 1972] 8171/73 Heading E1G An elongated polygonal sleeper block 2 for use closely spaced on a portable crane track rail 3 has an upper horizontal face less than half the area of a lower horizontal face, and a plurality of sloping faces extending from the upper face to eight or more vertical side faces whose height is less than half the total block height, four of the vertical side faces comprising opposed pairs at right angles while a further four or more vertical side faces are inclined to form an acute angle with the rail 3 and so leave space for a foundation packing tool. The sleeper block shown has stirrups 5 for rail-fastening keys 6. In a modification, Fig. 2 (not shown), the sleeper block has end rebates (2g, 2h) in its bottom face to reduce the bending moments applied to the sleeper.
