Sorry about that WWPM, I'm old school!

Is it possible for DW to transfer from wheelchair that I push to ride Tomorrowland Transit Authority? She can take a few steps (MS) after she's up with my assistance.
Is the ONLY way up to the ride vehicle the escalator or is there an elevator somewhere?
I think I already know the answer, but was hoping DISNEY has made the necessary accommodations.
TTA was always one of her chill-out rides where she could at least SEE the inside of Space Mountain since she can no longer ride SM, along with a peaceful ride above Tomorrowland!
