Abstract: A system determines real-time locations of railcars in a railroad environment. Railcars are equipped with at least four RFID tags. A RFID reader at a fixed location at every track branch in the environment reads the RFID tags. Railcar locations are updated for the railcars by determining the branches on which the railcars are located.

Abstract: In a vehicle cockpit module assembly having at least an air conditioner disposed inside a dashboard, a protrusion piece for determining an arrangement position of an air-conditioning unit of the air conditioner within the dashboard is provided at the air-conditioning unit. A front load support portion for supporting a front side load of the air-conditioning unit is constructed by a drain pipe of the air-conditioning unit, and a rear load support portion for supporting a rear side load of the air-conditioning unit is constructed by rear foot ducts of the air-conditioning unit. Accordingly, in the cockpit module assembly, the air conditioner can be stably supported in the vehicle.
