But the engineer cannot rely on the speedometer error. What if the error is the other way? What if when tested there is no speedometer error, but it is right on the money.When your job specifies to operate at 79 miles per hour, you do not intentionally operate at 80 miles per hour. It may get up there on a down grade, but the engineer *knows* that that down grade is there, and will have cut back power at the crest of the hill. Fuel efficiencies also come into play these days. The superintendent is going to be looking at his pocketbook more than his timetable these days. ROAR |
