feat(sleepers): the crossings at wide angles laid on timbers: where two tracks cross so wide they're laid as a grid, the one track carries timbers square to it through the crossing, two side by side under each rail of the other, which lays none there; the rail running along the two held on their seam by fastenings as far apart as the beams at most, clear of the fastenings of the rails across; the guard rails of the crossings at wide and middle angles held as the rails beside are, a running rail with its guard rail in the fastening of both, the rails crowding at the corners under one plate; the beams under the guard rails timbers as far as the guard rails reach; the fastenings selftest lists the rails on each timber with detail rails
