for guests. It was determined after delivery of Mark VII Monorail Red that platform clearance was too tight for the new, elongated end-compartments, so Monorail Blue was modified at the manufacturer and entered service before Red . Safety Emergency evacuation Emergencies requiring train evacuation will be handled differently depending upon the location of the train and the nature of the emergency. If a train is stopped at a station platform or the work platform, guests can exit the train onto the platform. Exiting a train is possible even when the doors of the train cars are closed. A cast member outside the car can also forcibly open the rightmost door panel of the car by releasing the air pressure holding that panel closed. The air pressure release is a handle beneath the rectangular center window that is similar in appearance to a car door handle. If a train is stopped on an open beam, then guests evacuate through emergency exits located in the roof of the train. Guests open roof hatches by first removing decorative plastic from the ceiling above a bulkhead footstool and then by lifting open a hinged hatch that will flip across the bulkhead dividing two train cars. Guests evacuate to the roof by climbing through the open hatch onto the top of the train. The bulkheads separating cars are designed as firewalls that will contain a fire within a car to just that car. The open hatch allows guests in the affected car to transfer to an adjacent car where they can safely wait for evacuation by fire response crews. If the emergency affects the entire train, then guests are evacuated to the surface of the beam. Guests again open the emergency roof hatches but do not simply move to the adjacent car. Instead, they use a small handrail present along the top of each train car to move to the front of the train. The Disneyland Fire Department assists in the safe evacuation of the disabled train. Platform safety Platform gates are operated manually and remain closed until the next train arrives and cast members determine that it is safe to board. The trains are powered by 600 V DC electric current, drawn from a small rail (bus bar) running along the right side of the beam. This bus bar is similar to the electrified or "third" rail of a subway train. Facts and figures
