A single-track railway is a railway where trains traveling in both directions share the same track. Single track is usually found on lesser-used rail lines, often branch lines, where the level of traffic is not high enough to justify the cost of constructing and maintaining a second track.

In railway signalling, a token is a physical object which a train driver is required to have or see before entering onto a particular section of single track. The token is clearly endorsed with the names of the section to which it belongs.

The normal practice is to provide a single line with passing loops or short double track sections to give trains running in opposite directions places where they can pass. This page gives an overview of the operation of trains over a single line and covers both US and UK practice.

Aug 1, 2012 · The single track line features passing sidings every 15 miles between 40 siding centers where trains can meet and overtake each other. The double track line features 45

On a railway, single-line working [1] refers to the practice where, when one line out of the two lines is blocked, trains are able to use the other in either direction. [2] This is usually when a line is out of use for maintenance, or because of damage, obstruction or train failure.

Sep 10, 2024 · Generally used for a general line, the single track carries up and down trains using only one track. Normally, it enforces the nature of the turn of trains by signals, or the passing loops may be used as a means where one train waits for another.

Nov 28, 2006 · It is single track, CTC, with sidings about every 7-10 miles. On the other hand, the CN (ex GTW) line from Toronto to Chicago is double track except for about a 8-10 mile section from Sedley to Lincoln (Valparaiso). It typically sees 30 - 35 trains per day.

Apr 1, 1996 · This paper describes the development and use of a model designed to optimise train schedules on single line rail corridors.

Scheduling of trains on a single line involves the use of train priorities for the resolution of conflicts. First, a mathematical programming model is described. The model schedules trains over a single line of track when the priority of each train in a conflict depends on an estimate of the remaining crossing and overtaking delay.

Jul 28, 2015 · Single-tracked lines are constrained in the number of trains they can carry by the number of sidings, spacing between them, and siding length, not to mention the general condition of the line and other design features that limit train speeds.
