Study Notes
Railway System
- A terrestrial-guided mass transport system where trains move on their own (diesel traction) or through remotely transmitted power (electrical traction) using steel wheels on a dedicated steel guideway defined by two parallel rails.
Tracks and Sleepers
- Sleepers are placed to preserve gauge between two rail tracks.
- Wheel loads are evenly distributed to the ballast by sleepers, which are placed on top of it.
Electrification
- Rectifier converts AC power into DC power for distribution to trains.
- AC is a train electrification system favored for high-speed and long-distance trains.
Railway Signaling
- Introduces an artificial separation between trains by dividing the track into distinct blocks.
- Each block represents a specific section of the track, and only one train is allowed within each block at any given time.
Buildings and Facilities
- Provide passengers access to trains at a particular location and include the station, station platform, escalators, elevators, and other facilities within stations and the depot.
Railway Infrastructure
- Earthworks refer to all aggregate constructions, whether natural or man-made, designed to ensure the rail corridor drains freely.
- Railway Fencing refers to the barriers or structures erected along the railway lines to prevent unauthorized access onto the tracks and ensure safety of pedestrians and vehicles.
Station Classifications
- Terminal Station: located at the end of the railway lines, where trains terminate their trips, often located near the depot.
- Connecting Station: one of the station classifications with two or more connected stations within proximity of different railway lines.
Rolling Stock
- Traction Lift is a basic part of Rolling Stock used in electrically powered rolling stocks that collects current from the overhead lines, electric third rails, etc.
- Bridges are structures carrying a road, path, railroad, or canal across a river, ravine, road, railroad, or other obstacle.
Other Railway Components
- Points and Turnouts enable vehicles to be diverted from one track to another.
- Public Address Systems serve as the primary method for regulating passenger flow, aiding in boarding trains, and facilitating evacuations during emergencies.
- Closed Circuit Television is essential for control rooms and emergency services to monitor activities on the ground and manage passenger flow.
This quiz covers the basics of railway transport systems, including the role of sleepers, rectifiers, and wheel loads in ensuring smooth train operations.
