A packed Admiralty MTR station. The system in Hong Kong carried 1.9 billion passengers last year, while its overseas operations carries nearly as many: 1.8 billion, or 5.6 million daily. From solely a local rail operator in 1997, it has become a transport giant with a 17,600-strong workforce in Hong Kong, and nearly 10,000 staff around the globe. Photo: K.Y. <PERSON>
