Mumbaikars' underground travel on the Colaba-Bandra-SEEPZ Metro-3 corridor will be further smoothened as the Mumbai Metro Rail Corporation (MMRC) has begun trial production of High Vibration Attenuation Booted Twin Sleeper Blocks to lay tracks with the help of Swiss machinery installed by M/s Sonneville from Switzerland.

The Sleeper Blocks are being cast with the help of state-of-the-art technology – at a facility set up at Wadala and one more machine is expected soon.
