The British English term for a railroad tie — the rectangular wooden or concrete beam that lies perpendicular to the rails, keeping them in place and the correct distance apart. 'Railway sleeper' is standard in UK, Australian, and New Zealand English, while Americans say 'railroad tie' or 'crosstie.' Old wooden railway sleepers have become popular in UK gardening as rustic raised-bed edging material.
The garden path was edged with old railway sleepers that had been salvaged from a disused line.
