Gauntlet track or interlaced track (also gantlet track) is an arrangement in which railway tracks run parallel on a single track bed and are interlaced (i.e. overlapped) such that only one pair of rails may be used at a time. Since this requires only slightly more width than a single track, all four rails can be carried on the same crossties/sleepers. Trains run on the discrete pair of rails appropriate to their direction or loading gauge.
The term gauntlet is derived not from gauntlet meaning a type of glove, but from the expression running the gauntlet (originally running the gantlope) which means running between two confining rows of adversaries; gauntlet in this sense is a "corrupt form".
Famous quotes containing the word track:
“He was good-natured to a degree of weakness, even to tears, upon the slightest occasions. Exceedingly timorous, both personally and politically, dreading the least innovation, and keeping, with a scrupulous timidity, in the beaten track of business as having the safest bottom.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
