Taizhou Rail Transit

Taizhou Rail Transit is an urban rail transit system in Taizhou, Zhejiang Province, China. The system is operated by Taizhou Rail Transit Construction and Development Co., Ltd. In the near term (Phase I), two lines, S1 and S2, are planned; in the long term, lines S3 and S4 are planned. The first phase of the plan was approved by the National Development and Reform Commission of the People's Republic of China in December 2014, and approved by the Zhejiang Provincial Development and Reform Commission in September 2016. Construction of Line S1 started in November 2016 and lasted until opening in December 2022.

Nomenclature
In the PRC both the terms (Urban-Suburban railway) and  (Prefectural area railway) refer to newly-opened commuter/regional railway services. These terms are usually interchangeable and are designated with the Latin letter S. In Southern Zhejiang province, however, shìjiāo tiělù refers to genuine commuter/regional lines like that of Transilien, while shìyù tiělù, dubbed with S, refers to partially underground urban systems like that of the RER. Taizhou, in particular, has both systems in its rail transit in operation; while Wenzhou has both a RER-like system in operation and a planned rapid transit. The RER-like system has everything similar to a rapid transit in terms of operation, and has no direct connections with the national railway system, yet still has a loading gauge and signaling system inherited from the interprovincial railway and runs on the left track, and comes with a longer distance between stations (approximately 3 km). Due to the state restrictions on rapid-transit building in smaller cities some city governments use this methods to circumvent such restrictions, branded as a rapid transit toward the citizens while as a commuter rail toward the central government.
