Systems, methods, and other embodiments for removing contaminated materials such as asbestos from railcars (i.e., train cars and subway cars) for subsequent recycling of the railcars. In particular, a collapsible inner containment structure having a HEPA negative air pressure is used. A door on the inner containment structure is opened at one end of the inner containment structure and a railcar is transported into a work area located within the inner containment structure. The door is then closed so that the inner containment structure can maintain the negative pressure within the inner containment structure. The contaminated materials such as asbestos are removed from the inside of the railcar using a mixture of pressurized water and media.
