Alameda Street, in the LA Terminal (north of 92nd Street/Tweedy) was rule 93 territory, as was all of Alameda south of there in the "road" territory, no ds, but happened all of the time blocking big east west arterials in the days before the 105 Freeway. Which is one reason why we started working on the Alameda Corridor, all the way back in 1983, when I was still with SP.

Used to hit cars down there all of the time, too. I had a car T-bone me at Nadeau Street, didn't see the two story locomotive stopped in the middle of the crossing, waiting for my pinpuller to throw a switch, and put a two by two inch "dent" in my fuel tank, while totaling his Gremlin, even bending the back struts on his hatch back..... Other than that big brown spot on his seat, he was uninjured.

Auto parts and auto rack trains were long and would block streets like Firestone coming over from Industry, via Los Nietos, via Norwalk, when they were told to wait by the trainmaster at Tweedy, usually because the Tweedy jobs were working.

The GM plant is long gone, along with places like Jorgenson steel, there is very little of carload business left (that would employ up to 5 jobs per shift, back in 69 when I hired out) in the industrial district around J yard (north of Slauson). Nowadays UP and BNSF stack trains rumble almost continuously up and down the trench all day from Dolores.

I've been on two special passenger runs through the Alameda corridor in my second career. And if they ever run one of these specials again, and you can finagle a ride, do it. It is an amazing piece of engineering and an amazing view of RR ops in the Harbor.
