Abstract
A railway maintenance car is provided for elevated railways which uses the rails, or rail of a monorail system, to move to the place of maintenance, thus avoiding obstruction of ground areas beneath the railway. The car of the invention includes telescoping cantilevered maintenance access platforms movable laterally and longitudinally of the car to place maintenance personnel alongside stalled cars on the rail or rails, and to move such personnel under the rail itself for maintenance and repair. The telescoping features of the invention include independently operable devices at each end of a telescoping platform in order to extend such platforms at an angle to the axis of the car for accommodating curved rail access.
