Semi-high-speed trains

Semi-high-speed trains are trains that operate faster than regular commuter trains, typically traveling between 160 to 250 km/h (100-155 mph). They are designed for regional travel, connecting cities that are relatively close together—usually within a few hundred kilometers—faster than conventional trains but not as fast as high-speed rail. These trains often utilize specialized tracks and modern technology to reduce travel time, making regional travel more efficient without the extensive infrastructure investment required for high-speed lines. They offer a balanced solution for faster travel with cost-effective infrastructure, improving regional connectivity.
