Fan track

from Wikipedia, the free encyclopedia

Round locomotive shed in Selzthal station with fully encircling track fan

In rail transport systems, a fan track or beam track is an arrangement of several track ends in such a way that they converge towards a common central circular point. This arrangement resembles the geometric shape of a fan. This radial track arrangement is often found at the turntables of roundhouses, which are located at the intersection of the tracks.[1]

Fan tracks are distinguished from track harps in that they are butt-ended, while track harps are “individual tracks arranged in parallel that contract back into a single track”.[2]
