It’s apparent that SP still enjoyed a considerable citrus traffic at Covina. In the distance, about 10-15 cars ahead of the engine, on the north side of the track can be seen the standpipe use for watering steam locomotives. Covina lay at the bottom of a grade that extended to San Dimas and La Verne and PE issued special instructions to address operations using retaining valves as well as maximum speed.
