SWITCHING STEP OBSERVATION SYSTEM A switching step observation system allows an operator in the operator station of a train locomotive having a full width nose cab to observe any activity on and around the switching steps at the front of the locomotive, even though the full width nose cab obscures the direct view of the switching steps. The system provides a small secondary mirror which is visible in the large rear view mirror which is standard equipment already present adjacent to the operator station. This small secondary mirror is mounted in such a position that it reflects an image of the switching steps to the operator by way of the large rear view mirror. Preferably, the small secondary mirror is mounted to be adjustable about two axes, so that the operator can easily adjust the mirror to obtain the optimum view. If switching steps and a rear view mirror are present on both sides of the locomotive, the system may be duplicated on both sides of the locomotive, so an operator can see both sets of switching steps from one position.
