1.The Instroduction Of Track Gauge
A.What is the track gauge?
The gauge of a railway track is defined as the clear minimum perpendicular distance between the inner faces of the two rails.
B.How many track gauges are there in the world?
The different track gauges can broadly be divided into the following four categories:
1. Broad Gauge: width 1676 mm to 1524 mm or 5’6” to 5’0”
2. Standard Gauge: width 1435 mm and 1451 mm or 4’-8⅟2”
3. Meter Gauge: width 1067 mm, 1000 mm and 915 mm or 3’-6”, 3’-33/8” and 3’-0”
4. Narrow Gauge: width 762 mm and 610 mm or 2’-6” and 2’-0”.

2.The Application Scenario Of Digital Track Gauge
A.The Digital Track Gauge is widely used in the stage of track laying and track maintenance .
a. The stage of track laying: The digital track gauge is used for measuring the track gauge,check rail gauge,back to back distance,cant（superelevation) and makeing the the measured parameters meet the track-laying standards.
b.The stage of track maintenance: The digital track gauge is used for adjusting the track gauge,check rail gauge,back to back distance,cant（superelevation) to reach the standard range,keeping the highest levels of accuracy and certainty,ensuring the train run safely.
B.The digital track gauge is apply for the railway lines,local railways, subways, urban rail transit, mines, steel mills.
C.The digital track gauge can be used during the day and dark night, rainy day and snowy day.
