VARIATIONS OF ENGINE TRAIN NUMBER INDICATORS

The placement of the train number indicator on the top of the smokebox by the stack is an iconoclastic signature of UNION PACIFIC RAILROAD locomotives. It may come as a surprise to learn that this was only one of several locations considered early in the Harriman Era. Until I came upon these drawings, I had never considered the possibility. In hindsight, it makes sense that some experimentation was done prior to selecting the position of the train indicators.
