The La Mesa Model Railroad Club at Balboa Park's San Diego Model Railroad Museum, models the Tehachapi loop Mojave to Bakersfield, they are still working on the layout as long as the museum has be operating. Track is done, scenery is still being worked on. They have operating sessions 4 times a year(50-60, 70-80 and Modern) Today's Operating was set as the day December 21st 1952, the time of day was flipped flop, so 12:00 pm was really 12:00am, and the trains that ran, they modeled they to the exact consist. If th train had a 2 hour layover, guess what the crew sits for 2 hours, if you were late, your late, if. The one difference between the real Mojave to Bakersfield and the LMMRRC model is the track mileage is shorter.
Another Layout is privately owned by a All Gauge Toy Train Association Member, Pat Archer. Pat has a nice property with trailers of Canoes and Kayaks for his Boy Scout Troop still being active in his mid 70s, with 143 Eagles he had the privilege to Mentor. Right when you walk in his house, there is shelves of Post war Lionel, proceeding towards his layout, the layout has to be at least 40 by 20(that is the 2nd Level), with most Lionel Accessories, Now the room has shelves everywhere of trains that might not run on his layout or he has no room to put cars on his layout. Special designed Roundhouse and Turn table with 21 2020 S2 Lionel Lines Turbines, 2 Main lines with 2 grades leading to the third level which has 2 lines set up that you might loose your train on level 3. He has a theme park named after him. Going down to the basement he has a layout that he and the team of guys that come and work on the layout are figuring out how to move stuff from level 1 to 2 to 3. Level 1 has a drag strip bunch of Industries, a river, and the layout was built over a pool so he drained the pool to put in the layout and has a storage spot under that layout. He is winding down to finishing the layout in the next 3 years.
