Railway - also known as railroad, is a mode of land transportation in which flange-wheeled vehicles move over two parallel steel rails, either by self-propulsion or by the propulsion of a locomotive.
CLASSIFICATION OF RAILWAY
CLASSIFICATION ON SPEED: Track Design Speed (Vd) - defined as the speed of the track alignment and corresponding railway infrastructure as a whole (superstructure, substructure, civil engineering structures, systems/premises) has been designed and constructed.
CLASSIFICATION OF RAILWAY
CLASSIFICATION ON SPEED: Operating Speed (Vo) - defined as the maximum authorized operating speed on a given section of line under normal conditions.
CLASSIFICATION OF RAILWAY
CLASSIFICATION ON SPEED: Maximum Authorized Train Speed (Vmax) - defined as the highest train speed that can be attained on a particular section of line under specified conditions.
CLASSIFICATION OF RAILWAY
CLASSIFICATION ON SPEED: Passage Speed (Vp) - which is defined as the constant speed with which a train passes from a particular, characteristic segment of the line which is of small length (e.g., passing through a tunnel, passing through stations, etc.).
CLASSIFICATION OF RAILWAY
CLASSIFICATION ON SPEED: Commercial Speed (Vc) which is defined as the ratio of the length of a railway route (usually between the two terminals or between two important intermediate stations) to the time it takes to cover it, including halt times at all intermediate stations and delays.
CLASSIFICATION OF RAILWAY
CLASSIFICATION ON SPEED: Average Running Speed (Var) - which is defined as the quotient of the length of a line segment (usually between two successive stations), to the time taken to pass this segment, considering normal traffic conditions (e.g., no unforeseen delays).
CLASSIFICATION OF RAILWAY
CLASSIFICATION ON SPEED: Rolling Stock Design Speed (Vrs) - which is defined as the maximum speed that, according to the manufacturer, can be developed by a particular type of locomotive, or with which a trailer vehicle can move.
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON FUNCTIONALITY: Interurban Railway - A rail system connecting different cities or towns, typically over longer distances, providing faster service than urban or suburban rail.
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON FUNCTIONALITY: Suburban Railway -A rail service primarily designed to connect outer residential areas (suburbs) to the central parts of a city, often catering to daily commuters.
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON FUNCTIONALITY: Urban Railway - Rail systems within a city, such as metro or light rail, focused on transporting passengers across short distances within the urban area.
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON FUNCTIONALITY: Steep Gradient Railway - A railway built to operate on routes with steep inclines or gradients, often using special traction or braking systems to safely navigate the challenging terrain.
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON THE TRACK GAUGE: Standard Tracks - This
category mainly comprises the 1435 mm gauge. This distance (4 feet and 8 inches) was established by the British engineer George Stephenson (1781–1848).
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON THE TRACK GAUGE: Broad Tracks - This
category mainly comprises the following gauges: 1,520/1,524 mm (former Soviet countries), 1,600 mm (Irish gauge) and, 1,665 mm, 1,667 mm
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON THE TRACK GAUGE: Meter Track Gauge - This category mainly comprises the following gauges: 914 mm, 950 mm, 1,000 mm (meter), 1,050 mm, 1,067 mm (Cape gauge).
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON THE TRACK GAUGE: Narrow Track Gauge - These gauges are usually used for secondary lines (industrial area, factory, mine service lines). Meter and narrow tracks are also termed as small gauge tracks.
CLASSIFICATION OF RAILWAY
CLASSIFICATION BASED ON THE TRACK GAUGE: Mixed Track Gauge - This category comprises tracks on which trains of different gauge category may run simultaneously.
