In order to realize the effective rescue of various complex rail transit accidents,the present situation and development trend of the existing rail fire rescue systems at home and abroad were analyzed through a literature search first. Then,the applicability of road and rail dual-purpose vehicles in mountain urban rail transit systems and the feasibility of modular transformation were summarized and analyzed. Finally,a new fire and rescue rail transit system was proposed,which was suitable for mountain urban rail characteristics. The results show that the designed road and rail dual-purpose fire rescue vehicle meets the requirements of track fire rescue. The system is adopted with a high-intensity modular and prefabricated design concept. It is equipped with a fire extinguishing and smoke exhaust system for controlling various fire conditions,a traction winch,emergency power generation,medical supplies,and other emergency rescue equipment,which can deal with the rescue work of track accidents in a closed and heavy smoke environment. The loss caused by accidents is significantly reduced.
