The new trainsets it has been confirmed that due to the single pan operation, they can now do 165mph with non constant tension wire. So much more of the railroad that currently offers only 135mph max operations can now run close to 160. Single pan ops eliminates the rear panto bounce at higher speeds as well as the rear panto bounce from two trains passing at high speeds.

Also the max curve speed for the new set is now 150mph vs 130mph of the old sets. Likely the rollout of these trains will be in current time slots, with trains that see the most ridership.

I'm confused... is this after they add fins to the pans? Or are you saying they don't need fins if they run without a "double pantograph order?"
The new power cars only have one pan each. And both power cars are buss bared together. The entire trainset only needs ONE pan to operate,

The curve at Deans to Midway will be 150mph up from 130mph. The section between Grace and Bush is next in line for high speed signal upgrade. the wayside boxes are all installed, it just needs to be cutover. Once that is done the two outer tracks that are good for 125mph will be brought up to higher speed ops.
