Introducing Liner Truck 3 — our latest fully electric tunnel vehicle.
- Tesla Model 3 battery and drive units
- Transports 22,000+ lb of concrete segments to the boring machine
- 28 miles of range
- 12 mph max operating speed
- Remotely piloted from Global OCC in Texas, with each pilot controlling/monitoring > 8 LTs in the field.
Fun fact: the same Liner Truck can carry standard freight containers through the tunnel.

“If it’s long, it’s wrong” is a core principle regarding part-lead times.
If you have long-lead parts, do everything possible to either find a new supplier, design them out, or bring the part in-house.
It’s about protecting future optionality — another non-negotiable principle.

VC7 is built to be a workhorse.
Almost every part of it has been improved over the previous generation.
Introducing Vertical Cassette 7 (VC7), our latest generation of continuous conveyor which transports muck/rock from the TBM to the surface.
- Height: 37 ft
- Weight: ~220,000 lb
- Max muck conveyance rate: 990 tons/hour (w/ 50% loaded belt)
- Max supported TBM advance rate: 4 miles/week
- Min Radius of Curvature: 500 ft (see 0:12 of video for a tight curve; maneuverability is critical in urban settings)
- Belt speed: 660 ft/minute
- Supported tunnel length: infinite (w/ "Belt Boosters" every 1.5 miles)
- 650+ improvements from VC6 focusing on setup speed, reliability, and power efficiency
Fun fact: for every 15 inches the machine mines, ~1 dump truck of material is generated!
