I guess it's good to upgrade the train system in China. A lot of people take the train in China, lot more than you'd imagine. At many times trains are so full (during holidays) that you'd need to wait a long time to get on one.

Besides, a train system is a much more efficient system to move mass people and mass goods across a vast land. It's better to upgrade the train system to attract the population to continue their habit of using train, rather than to encourage an increase in the per capital car ownership rate (even tho that'd definately continue to increase anyways).
