A barrier door may include a section including an outer stationary portion and an inner movable portion disposed within the outer stationary portion, an actuator, and a controller. The actuator may move the inner movable portion between different positions to control flow of air between a protective enclosure and a volume outside of the protective enclosure. The controller may monitor one or more operating characteristics of the actuator and may modify an operational status of the actuator to control the flow of the air between the protective enclosure and the volume outside of the protective enclosure based at least in part on the one or more operating characteristics.

Enclosure for a vehicle system

A barrier door for a protective enclosure includes a lower section and an upper section operably coupled with the lower section, and a ventilation system disposed within the lower section. The ventilation system includes one or more blowers and a plenum. The ventilation system is configured to direct air one or more of into or out of the protective enclosure.

A barrier door for a protective enclosure includes a lower section and an upper section. The upper section includes an outer stationary portion and an inner movable portion disposed within the outer stationary portion. The outer stationary portion and the inner movable portion are light transmissive. The inner movable portion is movable in a vertical direction and is coupled to a lift device disposed in the lower section. The lift device is configured to move the inner movable portion between a lowered position in which the inner movable portion is at least partially withdrawn into the lower section to form an opening in the upper section and a raised position in which the inner movable portion is extended to close the opening.
