Track spacing - Wikipedia
WEBThe 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.

WEBSep 25, 2023 · Standard gauge is 4 feet, 8-1/2 inches. This is the gauge used when steam railroading began. It became the common gauge of Britain, North America, and Western Europe — except for Spain, Portugal, and Ireland. But how did this seemingly odd width become standard?
Track gauge - Wikipedia
WEBIn rail transport, track gauge is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks.

Track gauge in North America - Wikipedia
WEBTrack gauge. The vast majority of North American railroads are standard gauge (4 ft 8⁄ in / 1,435 mm). Exceptions include some streetcar, subway and rapid transit systems, mining and tunneling operations, and some narrow-gauge lines particularly in the west, e.g. the isolated White Pass and Yukon Route system, and the former Newfoundland Railway.
