Walt Disney's 'trailer' gap-fillers
 

Disneyland's Monorail made its debut in 1959. The accordion gap-fillers have been in my memory since then, when I got to experience the system firsthand.
This technology dates to at least 1951, when intercity bus lines used it on the West Coast. I didn't come along until the year after.
It remains a bird in hand.https://d23.com/a-to-z/monorail/

Maybe in Denton.

I can ride the EMX any time for free due to my advanced age. www.ltd.org/system-map/route_103/

Little kids love to ride in the seats on the turntable. :thumbup:

Back in the late 50s we rode the flex bus from Pueblo, CO to Denver, CO (about 100 miles). The drink/snack station was on the turntable with hostess's to serve us.
