ABSTRACT:
A method and apparatus for testing watertightness of a railcar comprises a blower fan apparatus with an exhaust duct and an exhaust outlet that can be sealed against an aperture in the railcar. The fan blower of the apparatus is capable of providing an airflow to the railcar to provide a pressure differential of between about 0.5 to about 2.5 inches of H.sub.2 O between an interior of the railcar and an exterior of the railcar. The blower is operated to provide air to the railcar to provide a pressure differential, causing bubbles to form in a liquid solution applied to the exterior surface of the railcar. The railcar is marked for subsequent repair at locations where bubbles are detected.
