• Abstract:
  The report is the first in a series of engineering studies on railroad vehicle wheel performance. Preliminary studies are summarized, involving evaluation of actions taken to respond to high rates of crack occurrence observed in the wheels of certain multiple unit (MU) power cars used in commuter service. The conclusions of the studies were that the actions taken to address the observed problems were timely and appropriate. These actions were: 1) improvement of maintenance to prevent brake shoe misalignment and dispatching of cars with inoperative traction motors; 2) daily visual inspection of wheels to detect thermal cracks; and 3) immediate retrueing of thermally cracked wheels with center tread cracks longer than 1/2 inch or rim edge cracks of any size.
