context_page_description: 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 center-to-center spacing to differentiate it from the edge-to-center spacing of a railway. These two values may be different depending on how signal masts are added to the overall track geometry.
context_section_description: By definition the track spacing is given from center to center of a rail track. For an actual construction the distance is measured from the inside of a rail head to the matching one of the other track. As far as both tracks have the same gauge this is the same distance.
