How about Shenzhen Metro Line 3 Operation Branch?

Metro Line 3, also known as the Universiade Metro Line, is the subway line with passenger flow second only to Metro 1 Line (envelope) and Metro Line 4 (longhua line). The line is a state-owned enterprise authorized by the municipal government to operate rail transit, and is fully responsible for the operation and management of Longgang Line 3 and the preparation of a new rail transit line. The operation branch of Shenzhen Metro Line 3 was established in June 2008, and its business scope covers urban rail transit operation and traffic organization, passenger service, equipment and facilities maintenance, it system construction, consulting and training, and property management.

The Longgang Line (Line 3) currently operated by the company is a "Universiade Line" built by Shenzhen for hosting the 26th Universiade in 201/kloc-0. During the Universiade, Metro Line 3 successfully completed the Universiade traffic guarantee task entrusted by FISU and Shenzhen Municipal Party Committee and Municipal Government, and its first-class safety and service level won wide praise from all walks of life and international friends.

The prospect is still good.
