What is "t-series"

The T-series rapid transit cars (widely known as the T1 as only one production run was made) are a Toronto subway car model, ordered in 1992 and built in 1995–2001. The cars were built by Bombardier Transportation's Thunder Bay Works for the Toronto Transit Commission. Before the T-series, the TTC had been buying the H-series cars manufactured by Hawker Siddeley Canada and later Urban Transportation Development Corporation (UTDC).

T-Series is a music label owned by Super Cassettes Industries Private Limited (SCIL), an Indian music company which is also engaged in film production and distribution. It has ventured into other consumer product categories including manufacturing incense sticks (Rajni Industries) and washing powder (Gopal Soap Industries).
