On the left is an MTH RS-3 PS3 engine. On the right is one of the new WBB RS-3's. Both engines are pointing in their respective forward directions (moving left to right) as defined by: 1) initial direction on throttle up, 2) the way the cab figures are facing in the WBB engine and 3) the coupler firing sequences for the MTH engine. Is there a mistake? Or did Alco produce both cab-forward and cab-aft versions of this engine depending upon task?
