Canted curves (also known as superelevated curves) are railway curves where the outer rail is raised above the inner rail. This helps counteract the lateral forces generated when a train travels through a curve. They are a standard feature of modern railways and are designed to provide smoother, safer, and more comfortable operation at moderate to high speeds, while also reducing wear on wheels and rails.
Reproducing this feature in N scale can be challenging, but KATO's UNITRACK Curved Double Track accurately replicates this distinctive railway feature while maintaining the convenience of our easy-to-assemble UNITRACK snap-track system.
Approach Tracks and Banked Tracks
To assemble canted curves correctly, it is important to understand the difference between approach tracks and banked tracks. Approach tracks are used to transition between straight track and banked track. They gradually increase the cant of the track, creating a smooth transition between level straight sections and fully banked curves, just like on the real railway.
To ensure the tracks are connected correctly, check the centre section of the approach track:
- If the centre of the track is tilted, connect that end to the banked track.
- If the centre of the track is level, connect that end to the straight track.
Tilted centre:
If the centre is uneven and tilted, then this side needs to be connected to the banked (superelevated) track,
Level centre:
If the centre is horizontal and level, then this side needs to be connected to the straight track.
Although the tracks can still be connected if installed the wrong way around, you may notice increased resistance when joining them together. If the connection feels unusually stiff, it may be because the banked side of the approach track is being connected to a straight track.
Top Tip:
On some approach tracks, a small grey square marks the level (non-tilted) side, which should be connected to a straight track.
On some approach tracks, there is also a small grey square marking the level side.
When incorporating canted curves into your layout, always use an approach track between any banked curve and a straight track.

Mini Diorama Workshop with members of the Leamington & Warwick Model Railway Society in partnership with KATO
This year at the International N Gauge Show 2026 in Leamington Spa, we will be hosting a Mini Diorama Workshop!
For just £5 per participant, beginners will have the opportunity to create their very first Mini Diorama with guidance and support from members of the Leamington & Warwick Model Railway Society. If you're interested in joining the growing Mini Diorama Circus community, we'd love for you to take part!
Or why not start your Mini Diorama journey at home this summer?
If you already have diorama materials at home, simply choose a Mini Diorama Base (either straight or curved) and start building. For complete beginners unsure where to start, the Mini Diorama Kit includes all the essential materials needed to create a realistic, natural scene.
To participate in the Mini Diorama Circus at the show:
- Write your name and contact details clearly on the underside of your diorama.
- Bring your completed Mini Diorama to the KATO stand.
- Visitors can then leave comment cards with messages about your work.
- Collect your diorama before leaving the exhibition.
- Participation is free and open to all ages and skill levels!
Further details will be made available through the Mini Diorama Circus website:
