Railway vehicle makers expand overseas

When China's first subway, Beijing Line 1, went into operation in 1969, underground trains had been running beneath London for 106 years.

Despite the West's head start, however, Chinese train manufacturers have been enhancing technologies and designs, and have now become competitors in the global supply chain for urban transit.

Consider Boston, in the United States, which this month will receive its first batch of subway trains manufactured by China for the new Orange Line.
