Railway Track Types & Key Features
| Category | Type | Characteristics | Applications |
|---|---|---|---|
| Track Structure | Ballasted Track | Uses crushed stone (ballast) for drainage/vibration damping; low cost, high maintenance | Conventional lines, freight routes |
| Slab Track (Ballastless) | Concrete base, high stability, minimal maintenance, expensive | High-speed rail, urban metro | |
| Gauge | Standard Gauge (1435mm) | Global mainstream (China, Europe, North America) | Most mainlines |
| Broad Gauge (e.g., 1676mm) | Enhanced stability (India, Russia) | Heavy-load or specific regions | |
| Narrow Gauge (e.g., 1067mm) | Suits tight curves (Japan, mountain railways) | Local/mining railways | |
| Rail Weight | Light Rail (<50 kg/m) | Lower load capacity | Branch lines, sidings |
| Heavy Rail (≥60 kg/m) | High strength (e.g., U71MnG for HSR) | Mainlines, HSR | |
| Sleeper Material | Wooden Sleeper | Good elasticity, short lifespan | Heritage/temporary lines |
| Concrete Sleeper | Durable, cost-effective | Modern railways | |
| Steel Sleeper | Corrosion-resistant, high load-bearing | Bridges/tunnels |
