Assam railway maximum speeds map. Colour-coded rail lines by permitted speed — see which corridors support 200, 250 or 300+ km/h and where the network slows.
Assam railway network colour-coded by maximum permitted line speed, from slow branch lines to very high-speed corridors above 300 km/h. Speed data reflects the infrastructure limit, not the operating speed of any specific train service. High-speed lines (200 km/h and above) are typically purpose-built or heavily upgraded; slower sections reflect older rail infrastructure, tight curves or mixed-traffic constraints. Use the speed range filter to isolate specific bands — to identify lines capable of 250 km/h and above, or to pinpoint speed bottlenecks on otherwise fast corridors.
