Work on installing high-speed rail tracks for India’s first bullet train corridor has commenced, marking a key milestone in the Mumbai-Ahmedabad project. The line will use a ballastless “J-Slab” track system derived from Japan’s Shinkansen technology, being deployed in India for the first time.

Japanese Technology Adapted for Indian Conditions

The ballastless track system being adopted is designed to deliver stability, durability and precision required for trains operating at speeds of up to 320 kmph. It comprises four primary components: a reinforced concrete (RC) track bed, cement asphalt mortar (CAM), pre-cast track slabs, and rails fitted with specialised fasteners.
