WHAT? YOU SERIOUS? YOU’RE PULLING MY LEG!

A PAIR OF TROLLEYS FOR A STEAM LOCOMOTIVE

No, I am not pulling your leg. At least not this time. The LA & SL RR operated under the wires of the electrified freight lines of the Pacific electric railway in the Los Angeles area. To facilitate the interchange of freight cars between the two lines, it was necessary to operate a steam switch engine under the P.E.wires. However, the signals in the electrified territory were activated by the trolleys of the P.E. equipment. Since the steam-powered locomotives of the LA & SL lacked trolleys, they could not activate the P.E. signals when operating under the wires. The obvious solution to this obvious problem is add trolleys to a LA & SL locomotive to activate the signals. The drawing shown above has the details of how the LA & SL  accomplished the addition. Can anyone guide me to a picture of the locomotive with the trolleys added. I know at least one exists, but I cannot remember where. If possible, I will add it to this Post.
