STANDARDIZATION OF TRACKWORK PLANS

This committee submits the following report of progress in connection with the standardization of trackwork plans. Plans for five new standard turnouts were submitted and approved for recommended practice. Also published and issued for inclusion in the Manual were the various other AREA plans incorporating revisions in switch details. A study was made of the method used in calculating the recommended maximum speeds of trains through level turnouts. The AAR research staff made a study as a result of this investigation on standardization of turnouts. The formula developed by them used the angle of impingement at the point of switch, and an experimentally determined maximum lateral acceleration for comfortable riding, to develop the permissible speed through the switch. Speeds calculated by this method were compared to the recommended speeds now in the Manual and were found to be similar. Revision of a plan covering swtich stands was recommended.
