Track geometry is three-dimensional geometry of track layouts and associated measurements used in design, construction and maintenance of railroad tracks. The subject is used in the context of standard, speed limits and other regulations in the areas of track gauge , alignment, elevation, curvature and track surface.
For example, North America uses the reference rail as the line rail which is the east rail of tangent track running north and south, the north rail of tangent track running east and west, the outer rail (the rail that is further away from the center) on curves, or the outside rails in multiple track territory.

The 300 metres is an uncommon (meaning not on an Olympic or World Championship program) sprinting event in track and field competitions. The race starts on a straight and therefore comprises two straights and one bend.
The proper length of the first lane of a competitive running track is 400 m (1,312.3 ft). Some tracks are not built to this specification, instead being a legacy to imperial distances such as 440 yd (402.336 m), equivalent to a quarter of a mile.
The high school version uses a standard 45 meter start to the first hurdle. Thus the high school race is equivalent to beginning of a standard 400 meter hurdle race, but its placement on the track is shifted 100 meters around the track so it finishes at the common finish line on the straightaway, where the longer race would reach the same point near the end of the second turn.
In 2006, possibly due to cooler weather conditions and better track conditions, Top Fuel driver Tony Schumacher set a new NHRA national speed record of 336.15 mph. Following the 2006 NHRA season, National Trail Raceway ceased hosting a national event and the Pontiac Performance NHRA Nationals was moved 100 miles north to Summit Motorsports Park ...
