The TESI Locomotive Refueling Side Spill Pan is a 60-inch by 22-inch by 6-inch portable pan that can be positioned by one railroad worker and used for locomotive refueling. It has a 9-inch and a 14-inch flap that hug the fuel tank of the locomotive during refueling to help catch fuel rundown. These flaps close to keep rainwater out of the pan when not in use. This fiberglass pan weighs only 65 lbs. and it can be equipped with two wheels on one end for easy movement over track ballast. Units may be transported to the refueling site by the fuel tanker truck or it can be left on-site.
