We developed a model running facility to study the flow of the under-floor of railway car. The facility was set up in the test section of the Towing Wind Tunnel Facility where by a hood we can eliminate disturbances, such as natural wind. We carried out the model running tests and measured the velocity distribution under the model car. The velocity distribution was almost the same as in the rear cars from the car No.3, and the velocity between the rails was less than the velocity outside of the rail.
