A railroad signal maintainer performs routine adjustments on a Model 5H switch machine. The machine allows remote operation of track switches from an central office location, sometimes hundreds of miles away. Built into the machine is not only the motor and related components to throw the switch, but electrical contacts that allow the system to verify that the switch is within proper adjustment. An improper adjustment of even a fraction of an inch can result in a derailment. This maintenance is performed at least monthly.

My HO model of Southern Pacific (SP) 9016 was leading a westbound local, switching "Tuolumne" on the California Central Model Railroad Club (CCMRC) in the historic Agnew depot in Santa Clara, CA on Saturday, November 28, 2015. This is an Overland Brass model.

The real SP 9016 was a Kraus-Maffei, ML-4000, SP Class DF-801. It became SP Class KF636-1 and SP 9119. Reportedly, it was built in 1964, construction number 19112. It was retired in 1967 and scrapped.

Lit by a pair of 580EXes: one high and slightly to the right on an umbrella, another way off right gelled warm and powered way down, both triggered by an ST-E2. And, of course, the shutter is dragged way out (4 seconds) to pick up the blinky lights.
