As millions of China’s citizens rise into the middle class, it will be interesting to see which wins out — the automobile or urban rail.
Some urban rail definitions:
- Street rail is any modern urban electric rail system that runs mostly on city streets, mingling with auto and pedestrian traffic. The cars are lightweight and run singly or in pairs.
- Light rail runs mostly on its own dedicated right-of-way, though it may take to the streets in short sections. Several cars may be coupled together.
- Heavy rail, found only in the largest cities, runs entirely in subways or on elevated right-of-way. The platforms are usually level with the car floors, and trains are longer.
- Commuter rail runs on regular railroad lines, and the cars are pulled (or pushed) by locomotives. The largest urban rail systems may combine all four modes.
