Hello Ak,
I like your last post #253, a very ingenious track plan indeed.
I may be missing something, but would it be possible to indicate the Zero elevation datum on that layout please?
Edit:
Don't worry I found it - the little markers alongside the track showing elevation - thank you.
I missed them until I clicked to enlarge the image.

Two German brothers' H0 scale Model railroad under a billiard table

Was this an inspiration for Density or just "great minds think alike"?

Above N scale design transferred to H0 scale:

A ruling grade of 3% is feasible on an area of 4 x 8 feet (ca. 1.2 x 2.4 m) as well as a depressed harbor basin. Between the scenic divider and the harbor basin there is still space for sidings on the top level. Each loop measures 10 m in length, so 20 m track length in total. Theoretically, the footprint can be reduced to 1 x 2 m, but then there is no room for the harbor basin or rail curve easements.

Why stop here? How up can you go? Sorry, I've been drinking Cava with dinner.

Roger

This NMRA description of a basic freight classification yard caught my attention. Amalgamating the NMRA scheme ...

... with an earlier twisted dogbone concept ...

... I came up with this 4x8 ft idea:

The proximity of a big city serves as a pretext for the dense trackwork and operations of various trains. For ease of operation and minimal fouling of the mainline, the yard operates in a one-way mode. Assuming that the small classification yard is located between two larger ones (yard A and yard B) explains this arrangement: Trains originate from the distant yard A and are then hauled to the distant yard B. Freight destined to yard A is turned around - out of sight - in yard B.

The layout allows to break up a long US type freight train and serve various industries, while a passenger train could serve a suburban station (the upper deck trackage is open for interpretation and adjustments). A round trip for a train traveling the entire dogbone route measures 20 m and the arrival/departure ("A/D") track can hold a 4 m long freight train. A yard switcher can be parked on the yard lead tail track. With right-hand traffic, the uphill gradients are 3% steep and downhill slopes up to 4%

Never in the history of Marklin have I seen so many tracks on such a small space with so few houses.
Or something like that.

I am looking forward to seeing it...If it happens.
