Re sleepering where the ballast is otherwise sound can be done between trains a short train of open wagons would deliver the sleepers and if necessary new fastenings by simply trundling slowly through the section while the engineers pushed them off the side and dropped off a sack of fang bolts chairs and keys etc every so often
