TL;DR: If you were in 469's way in 2011, you were getting pushed, no questions asked.

The middle four wheels are fixed.
The front and rear pairs of wheels are pneumatically lifted or lowered
The front and rear wheels also have pneumatically actuated ball castors next to them, just inside the inner frame rail. I don't remember the exact pneumatic setup, what was independently controlled and what was not.
They also used 3-speed Dewalts that year, servo shifted. They switched to Supershifters this year.
That drivetrain was HEAVY.
