The difference between high-speed rail and ordinary railway

1, different railway tracks

The high-speed railway adopts ballastless track, and a few of them adopt ballasted track. Ordinary railway track is based on pebbles, and then sleepers or cement sleepers are laid, which is called ballasted track.

2. The distribution of power is different.

The trains used in the high-speed railway are power decentralized EMUs. Distributed power train is a traction mode of railway train, which is opposite to centralized power. Its characteristic is that the power source is scattered on the engines of each car of the train, rather than concentrated on the locomotive. Ordinary trains are towed by locomotives, which is a centralized traction mode.

3. The signal control system is different.

China Train Control System, referred to as CTCS. High-speed railway adopts digital control signal, which is more accurate and stable than traditional analog signal and ensures the safety of train operation. Ordinary railways use analog signals.

4. Different pricing and positioning.

The price of high-speed rail is higher. An ordinary train refers to a train whose speed is less than 200 kilometers per hour. Its speed is lower than that of high-speed rail and bullet train, and its price is relatively low.
