I am seeking clarification on the brake rigging for the Union Pacific B-50-20 boxcar. This is being done from a Westerfield kit. The underframe has a single center beam (Bettendorf I believe). A photo on page 78 of Volume One of the Focus On Freight Car series verifies that the brake levers passed through the center sill. This is in opposition to the arrangement on PFE refers using this underframe in which the brake levers were supported by stirrups under the centersill. The photo in the Focus On Freight Cafrs book is rather dark. I would suspect that the rod between the two levers is located on the same side of the centersill as the KC cylinder. I would like to confirm this prior to completing the car.
