A pocket track, tail track, or reversing siding (UK: centre siding , turnback siding) is a rail track layout which allows trains to park off the main line. This type of track layout differs from a passing loop in that the pocket track is usually located between two main lines, rather than off to the side.[1][2][3]
Pocket tracks also allow for the short-turning of trains, truncating services at an intermediate station to control train frequency.[4] They are also used at terminal stations to allow for the construction of future extension of a rail track without disrupting existing service.[5]
