After a Plexiglass divider was added to one ride vehicle as a test, now all of the trains of Mickey & Minnie’s Runaway Railway have dividers between rows.
The Plexiglass is between each row of a car, not between each car.
For now, Cast Members are still only loading one party per car, usually in the front row of each car.
Assuming the Plexiglass dividers are found to be safe and effective, two parties could share a car and the ride could increase capacity. The same happened with Star Wars: Rise of the Resistance at Galaxy’s Edge.
Watch our video of the Plexiglass dividers visible from the loading area below.
