Answer :
Final answer:
Different rail types like Railway Rail, Vignoles Rail, Flanged T Rail, and Grooved Rail are designed for specific environments and loads, with the primary differences being in their cross-sectional shapes and adaptability to varying conditions and uses.
Explanation:
In the context of railways, the differences between Railway Rail, Vignoles Rail, Flanged T Rail, and Grooved Rail are important for understanding the adaptability and usage of different types of rail tracks for various environments and applications.
- Railway Rail, often referred to as flat bottom rail, is the standard form of rail used for railways. It has a flat base, which is laid directly onto sleepers (railroad ties) with no need for chairs.
- Vignoles Rail is another name for the flat-bottomed rail and is widely used around the world. Its design allows for a greater bearing surface.
- The Flanged T Rail is the American standard rail design with a flat bottom and a T-shaped cross-section, which provides a stable base and can support heavier loads.
- Grooved Rail is utilized primarily in tramways or streetcar systems. It has a groove to accommodate the flange of the wheel, allowing trams to coexist with road traffic by being embedded into the street surface.
