Delhi Metro Turns 23 With First Train TS#01 Still in Daily Service

Rigorous overhauls, including a 2024 mid‑life upgrade, sustain the train’s reliability.

Overview

  • TS#01 has logged about 2.9 million kilometres and carried more than 60 million passengers, with roughly 2.4 million door operations.
  • The original four-car set was expanded to six coaches in 2014 and to eight in 2023 to accommodate rising demand.
  • Mean distance between failures stands near 85,000 kilometres, well above the 40,000‑kilometre contractual benchmark.
  • Regenerative braking recovers roughly 40% of power use, cutting energy consumption and emissions.
  • Built by South Korea’s MRM Consortium for about Rs 24 crore, the train was shipped to Kolkata and moved to Delhi via Indian Railways.
