Bottom terminal in the summer.Height-adjustable detachable terminal.Top terminal from below.Another view of the top.Doppelmayr Uni terminal.Looking down the line.Looking up the lift line.Bottom station from above.
You can also tell by the still-embedded towers. All Doppelmayr hsqs (that are completely new installs & do not reuse towers) that I can think of use bolted footings.
I’m curious why Sunrise Express only has 1,800 pph capacity when the other high speed quads around it all have 2,400 pph at minimum. It seems rather unusual for a base area HSQ.
This is the third base area. (Skyliner doesn’t have a lodge, but it’s the popular passholder lot.) Not used full season, has some beginner stuff, not really marquee. Also, longer load times is easier for them beginner types.
For a quad chair with an 1,800 rider/hour capacity, the chair arrival interval is one chair every eight seconds. In other words, a group of four people has eight seconds to get into position to load the chair after the previous chair passes. Mt Bachelor management, at the time of this Sunrise Express install, believed the eight-second chair arrival interval was appropriate for this lift given the novice terrain it serves and the skill set of the customers using it. A higher capacity lift – with a shorter chair arrival interval – would result in increased lift stoppages due to misloads, lowering the functional lift capacity such that the higher potential capacity would never actually be achieved. That was the thinking at the time.
Fast forward to today… the master development plan calls for a six-passenger lift in this alignment. A capacity of 2,400 riders per hour – a 33% increase over the current capacity – would allow for a nine-second loading interval. That’s one second more than the current quad… which would be helpful with six passengers loading & unloading instead of four.

Every tower with the exception of tower 1 was reused from the former Yan triple.

It’s almost like they stripped the sheaves off the original towers and then put the new tower lifting frames on top of them.
It really shows when you compare the towers on Sunrise to the same-year vintage Little Pine (formerly Sunshine Accelerator).

you are wrong, little pine has towers more like northwest

Also also, see above reused Yan parts from the old triple, maybe? Both are conjecture from a fan of but not employee of Mt Bachelor.

Maybe the old tower tubes weren’t strong enough.
