Mumbai–Ahmedabad Bullet Train Project

under construction

India's first high-speed rail corridor between Mumbai and Ahmedabad is progressing with the adoption of an advanced ballastless track system inspired by Japan's Shinkansen technology. The project deploys the J-Slab track system, replacing traditional ballast tracks with a rigid concrete structure, comprising reinforced concrete track bed, cement asphalt mortar, pre-cast track slabs, and rails with specialised fasteners. Dedicated track slab manufacturing facilities have been set up in Gujarat at Kim near Surat and in Anand, with ten operational track construction bases along the corridor. Around 185 route km of reinforced concrete track bed have been laid, with 188 km of track slab production and over 70 km of installation work completed.
