Meet the TBMs

Elsie and Soyeon, the twin Tunnel Boring Machines (TBMs) for the Purple Line Extension Section 1 are currently digging two parallel tunnels that will connect three new stations between Koreatown and Beverly Hills.

They started their tunneling journey Fall 2018 at Wilshire/La Brea Station in Miracle Mile and will continue towards Wilshire/Western Station in Koreatown. Once they reach theĀ current Purple Line terminus, they will be dissembled for transporting back to Wilshire/La Brea Station and then reassembled for the last leg of their journey through Wilshire/Fairfax Station and finishing at Wilshire/La Cienega Station in Beverly Hills.

The Section 2 TBMs, Harriet and Ruth, will start their tunneling journey in Spring 2020 from Century City/Constellation Station and head east towards Wilshire/Rodeo Station in Beverly Hills and link up with the Section 1 tunnels at Wilshire/La Cienega Station.
