3 x 7 N scale layout
A 3 x 7 track plan for all those who just want to see long trains running on ovals. I call it “6 trains on 2 loops”. And since we don’t want to do this on 2 boring parallel ovals, let’s design an urban scenery for it. After all, the underlying concept shouldn’t be too obvious:
What is it all about? This 3 x 7 N scale track plan is not made for shunting maneuvers. It’s designed to showcase running model train sets. A large station and a busy multi-track line are an ideal stage for this. We have sidings for 6 long trains.
All tracks run at ground level. There are no gradients. So this is also an interesting project for beginners. Both the city and the train station are located on covers above the tracks. The lids hide ugly tight curve radii and we have enough space to create atmospheric city sceneries.
My focus here was also on designing an appealing track layout with KATO N scale tracks. KATO is a very good system, but like all systems with standardized tracks, it can look unrealistically geometric. I managed this by using wide curve radii for the parade route (= KATO curves 20-150 and turnout 20-203). Narrow radii are (almost all) hidden.
Let’s reveal the secrets:
3 x 7 N scale track plan
Facts
- Size: 3′ x 7′. This corresponds to 91.4 x 213.3 cm (approx.)
- Tracks: KATO Unitrack
- Slight deviations in measurements are possible. Track planning software isn’t 100% accurate
- No slopes / inclines
- parade route with appealing wide curve radii (r=718 mm)
- Tight curve radii hidden
However, you must cut some straight tracks. More: KATO length modification (YouTube).
Let’s have a look at the operation diagram. Two simple ovals, that’s it:
There is also an interchange between the two loops.
Two dead end tracks within the station hall are intended for a commuter. The shuttle train leaves the station and returns soon afterwards:
