Track spacing information


The track spacing is the distance between the track centres of double-track railway lines. There are standard distances derived from the standard loading gauge in a country. For high-speed trains and in tighter curves that distance needs to be increased.

The track spacing is also called the centre-to-centre spacing to differentiate it from the edge-to-centre spacing of a railway. These two values may be different depending on how signal masts are added to the overall track geometry.
