The primary distinctions between heavy rails and light rails lie in rail weight, load-bearing capacity, and application scenarios.
1. Definition
Heavy rails: Designed for high-capacity vehicles, typically used in high-speed railways, intercity railways, and metro systems. These rails feature thicker profiles with stringent specifications to withstand greater forces.
Light rails: Employed for lighter vehicles, commonly in urban transit systems such as trams and light rail lines. Lighter in weight, they accommodate lower load demands.
2. Rail Weight
Heavy rails: Weight per meter usually exceeds 60kg, capable of supporting heavy train operations.
Light rails: Weight per meter typically below 24kg, suitable for light train operations.
| Classification | Height(mm) | Head (mm) | Bottom (mm) | Thick(mm) | Weight (kg/m) | |
| Light Rail | 8 KG/M | 65 | 25 | 54 | 7 | 8.42 |
| 9 KG/M | 63.5 | 32.1 | 63.5 | 5.9 | 8.94 | |
| 12 KG/M | 69.85 | 38.1 | 69.85 | 7.54 | 12.2 | |
| 15 KG/M | 79.37 | 42.86 | 79.37 | 8.33 | 15.2 | |
| 18 KG/M | 80 | 40 | 80 | 10 | 18.06 | |
| 22 KG/M | 93.66 | 50.8 | 93.66 | 10.72 | 22.3 | |
| 24 KG/M | 107 | 51 | 90 | 10.9 | 24.46 | |
| 30 KG/M | 107.95 | 60.33 | 107.95 | 12.3 | 30.1 | |
| Heavy Rail | 38 KG/M | 134 | 68 | 114 | 13 | 38.733 |
| 43 KG/M | 140 | 70 | 114 | 14.5 | 44.653 | |
| 45 KG/M | 145 | 67 | 126 | 14.5 | 45.546 | |
| 50 KG/M | 152 | 70 | 132 | 15.5 | 51.514 | |
| 60 KG/M | 176 | 73 | 150 | 16.5 | 60.64 | |
| Crance Rail | QU 70 | 120 | 70 | 120 | 28 | 52.8 |
| QU 80 | 130 | 80 | 130 | 32 | 63.69 | |
| QU 100 | 150 | 100 | 150 | 38 | 88.96 | |
| QU 120 | 170 | 120 | 170 | 44 | 118.1 | |
3. Application Scenarios
Heavy rails: Ideal for high-capacity and high-speed operations, including high-speed railways, subways, and heavy-haul lines.
Light rails: Suited for short-distance urban transit, often sharing roadways with other vehicles or operating on dedicated tracks.
4. Structural Differences
Heavy rails: Larger cross-sections withstand greater forces, optimized for heavy-duty operations.
Light rails: Simplified structures accommodate urban flexibility requirements.
In summary, significant differences exist in design, load capacity, and applications between heavy and light rails. Selection depends on specific transport needs and environmental conditions.
