In the late 1950’s and early 1960’s my parents moved adjacent to the old Pacific Electric track in Colton, Calif. That line regularly used I believe TR switchers of the Southern Pacific, in the 4600’s. A favorite was 4618. That unit had big can mars lights. The units lacked traditional handrails that skirted engine walkways.
An odd move for the TR’s was the water train that would climb up into the San Bernardino Mountains, and involved a runaround move near the downtown San Bernardino area.
Later, I saw pictures of those TR units in San Diego, on SP’s San Diego & Arizona Eastern.
A memorable childhood move was SP 4613 northward crossing Florence Ave. in the Los Angeles area, while my dad was having some kind of work done on our auto.
Hope there are a few old timers here at the forum from the Los Angeles area that can relate to all this, and that I made their day!
