Title: East LA, Pasadena & Cucamonga RT66 Layout (HO Scale)
Post by: Yannis on February 22, 2026, 06:31:28 AM
Hello everyone,

I have recently started re-assembling and building my layout after moving houses. Old layout was on the same theme, but much more compact (I rented) with modules built with the intention of fitting a future bigger plan. So now it is time for executing this bigger plan!

Thanks for stopping by! I ll be updating when progress is made.
Yannis

Some specs.
Room dimensions: 29'x21'
Track Specs: Peco Code 83 flex track, Min radius 36"-(38" for the mainline on the main peninsula)
Benchwork height and construction: 52" height, birch plywood + pine depending on the module.
Turnouts: 6"-7"-8" for mainline/passenger tracks, 5" used only for industrial sidings.

Era: 1968-1970
ATSF Pasadena Sub-division. Main scenes: Scenicked Staging Yard (LA or SB), Elysian Park, LA River Bridge, South Pasadena, Pasadena Depot/Industrial Area, Pasadena/Rt66 Colorado Boulevard Downtown Scene, Cucamonga.

Trains operating:

Current state of the "along the left wall" tracks and backdrop that i salvaged. I ll paint the wall behind the San Gabriel mountains and have the foam mountain proving a semi-3d effect.TheLayoutBackdropWIP1.jpeg

Scenes from the same modules in the previous layout (will be replicated)

I'll be following with interest: My first view of the LA area was from an ex-ATSF high-level coach on Amtrak's Southwest Chief when it still ran through Pasadena.  Recall seeing the LA Basin from Cajon Pass, full of smog with the tops of hills above it, then through the flat industrial zones that made me think "this is where they shoot Adam 12". I crossed the LA River bridge you're modeling. Didn't have a good camera then...

Wow Yannis that's going to be a spectacular layout when you finish it. You did very well with the mountains and it's coloring.

A couple of times I drove (from Orange County) to Pasadena to visit "The Original Whistle Stop".  I think you are capturing what I saw on those trips.

Looks like a nice layout concept.   Your backdrop painting fits the scene perfectly.

Yannis,

Great track plan and of course I'll be following along on this.

Love those blue SF geeps.

Thank you all for the motivating replies!!! They are much appreciated.

Dave i think the current Whistle stop is on Colorado boulevard, I guess we are referring to the same shop. It is one of my bucket list items to visit the States and go through these locations.

Speaking of Colorado boulevard, here is a photo of one of the main reasons that I picked Pasadena as the focal point of my layout, the crossing of Colorado boulevard by the ATSF mainline. One of the few cases where one can model a main street with a considerable amount of Art Deco / Streamline moderne buildings and a mainline at the same time.The downtown area/scene is on two modules on wheels that slot into place (in order to access the tracks along the backdrop when needed) and currently are waiting for longer legs in order to go back into their spot. Photo taken from the previous layout, but it will be identicalRT66ColoradoCrossing.jpg

This will be interesting to watch come together, Yannis.

You answered my question about access to the back of the downtown area.  Good thinking.

Cheers, Mark.

Howdy Yanis,

The layout design and diagram look terrific.  The layout looks to be a lot of fun.

I'll follow the layout thread with interest.

Have fun,
mike

This will be an impressive layout.
The sections you've already built are impressive.
That photo of the train crossing the grade is very realistic.

Mike, Mark and Rick many thanks for the kind words.

Some extra narrative on the track plan. I hope i do not bore with these details.

The staging yard is double ended and represents both LA and San Bernardino.

The small yard between Elysian park and the LA River Bridge, is based on SP's Midway yard, but in my layout is used by the ATSF. It also serves the purpose of hiding a reverse loop track if you notice.

The Diesel House, is not prototypical I am afraid, both SB and LA had TT/RH facilities. I had a few iterations of this trackplan with a reasonably prototypical TT/RH instead, based on Redondo junction but it occupied significantly more space (imho) on the upper right corner. I prefer more negative space and mainline running and a smoother transition from the yard to Cucamonga (going counterclockwise), so i replaced it with a Diesel house. Nothing is built yet, but i think the pros of the diesel house outweigh the cons. I already have the nice Walthers' diesel house kit, and it is much simpler to build this scene than the TT. Feel free to chime in on this.

The excursion steam powered trains, will be making a wine-tasting stop at Cucamonga. They will occupy the main while doing so. That troubled be a bit, but by the late 60s, the Super Chief crossed the line at Cucamonga either very early in the morning or at around 9pm. Local freights followed suit closely so somewhere midday i reckon it would be fine to make a long stop for wine tasting at Cucamonga without bothering anyone. Worse case scenario, i can add a spur off the Cucamonga siding, to move any boxcars parked at the dock of Cucamonga (by the preceding local freight) and have the excursion train park at the siding.

Looks like a neat plan Yannis, I'm looking forward to looking in on your journey with the layout..... :)
