In a locomotive cab structural damage due to collision, derailment or rollover may often block the normal egress routes. These situations require suitable emergency egress systems that provide access both from interior by the crew and from exterior by the rescue team. After incorporation of a removable roof hatch as the primary egress system, a removable windshield and emergency hinge release of the rear door were selected as potential secondary emergency egress alternatives. Simple innovative concepts and cost-effective hardware systems have been developed at Foster-Miller laboratories and installed on mockup assemblies to provide viable solutions to the above two secondary egress systems. Proof of concept demonstration and functionality evaluation were successfully carried out. This paper presents the salient design features and functional evaluation of these novel emergency egress concepts. Feasibility of incorporating these secondary egress systems into new railroad locomotive cab design is briefly discussed.
