This invention comprises improvements "in and connected with railway sleeper's'and atcatchments therefor and has for its principal object to provide animpro'ved form of steel- "regard to "the heavier "into more general use;

More "specifically one object is t provide a. sleeper of whieh'the seetion, when depressed *by a 1 0ad,tent1s to compact theyballast retaqined 'beneetththe "wings 'QInd with which the ballast is easily paokedowing to the facility with whie'h access is had thereunder, so that it' he'vsleeperean be befldetl withgreat security ex-rid high resistance is'oil'e 'ed to sleeper-creep. A ftrrt ero'bject is toproyide a sleeper whereare very accessible and eanQbe' adjusted- Without disturbing the sleeper or removing-ballast.
