Overview
- MMRDA says the Mandale facility spans roughly 32 hectares and is India’s first elevated metro depot built to support the 23.6‑km DN Nagar–Mandale Line 2B.
- India’s longest metro test track at 965 metres sits within the depot, with four shunting necks and one elevated neck to manage train movements.
- Sustainability systems include 175 KLD effluent and sewage treatment for water recycling, more than 100 km of underground utilities, and noise and dust suppression installations.
- Officials highlight engineering hurdles such as coastal soil conditions, the need for heavy‑vehicle access roads, and designing a compact double‑deck structure.
- Branded by MMRDA as “The People’s Depot,” the site is being presented as a public asset with invitations for residents to engage with its scale, technology, and sustainability features.
