Around the turn of the century some prosperous ranchers and farmers in Nicasio, CA (Marin County) decided that they needed a better way to get their products to market. A railroad was discussed, incorporated, and funded. The plan was to build from Nicasio to Bayside, a small but bustling port on San Francisco Bay.
The Nicasio Southern Railroad laid rails, started running trains, hired the wrong president, and he very quickly stole all the capital and absconded.
A group of San Francisco financial types saw an opportunity to take a functional railroad, and a territory rich with farms, ranches, fisheries, and lumber, and create a viable railway with connections to the national rail network as well as the Bay. The Nicasio Northern Railway was born, and at this time in history (mid-1920's) is a viable concern. Barely.
The Nicasio Northern starts at Bayside, which has the main passenger and freight yards and the engine servicing facility. Bayside is on a peninsula jutting into the Bay. The wharf and several industries serve the railway and southern Marin.
From Bayside we go north past Backdoor Junction, the connection to short eastern branch to Dither. Past Backdoor, the road continues north through the hills (literally) until we hit Skalville. Skalville is the junction to the NN Railway's eastern division, the town of Yawn, and the connection to the rest of the US rail network.
From Skalville the line heads north to the thriving metropolis of Nicasio, with its ranching and farms. Leaving Nicasio, we continue northward to Highland, which is another railway town. The tracks continue to Hither.
The Nicasio Northern railway weaves through the hills on muddy and slippery roadbed. Need I mention that this is earthquake country? Even if the right of way was once perfectly laid out with straight tangents and smooth grades and curves, it didn't stay that way. The little steam engines rock and roll as they lead their trains across the pike.
Track is complete and operational. The layout has a peninsula in the center of the 12 x 21 foot space, and the rest of the track runs around perimeter of the room. Bayside yards and the engine terminal are on the peninsula.
There is a short, but steep, walk from the corner to Jon's house in addition to two flights of stairs to access his train room.
