LAGGIES Basic Helix, Track radius 360/437.5 mm

Item No: 53004

Track radius 360 mm / 437.5 mm, 1- or 2-track,
base circle, 9 segments = 1 1/2 circles,
construction height: 130.5 mm,
segment width: 165 mm,
inner gradient: 3.8%,
outer gradient: 3.17%,
outer diameter (outer dimension from post to post): 998 mm

Suitable for: Märklin M / K / C, Trix C, Fleischmann Modell / Profi, Roco / Roco Line, Roco geo-Line, Piko A and other tracks with these radii.

Each track helix can be assembled with a right- or left-hand rise. The complete kit includes all the necessary stands, track segments, and detailed assembly instructions. You will need one base circle for each track helix. The number of required extension circles depends on the height you want to cover.

A spiral track - what exactly is it?
A spiral track is a spiral in which a train travels from one level to a lower or higher level. The train travels downwards or upwards in the spiral track. The spiral track has the same gradient at every point, allowing even long trains to easily negotiate large differences in elevation.

When is a track helix needed?
The possible applications are very diverse. Here are some examples:

• To reach a lower or higher level.
• To get to a shadow station below the layout.
• To connect two systems of different heights.

How is it ensured that trains don't derail on the curves of the track helix?
The outer curves of the track helix are raised by 3 mm. This significantly improves driving safety and reduces rolling resistance.

What variants of LAGGIES track spirals are available?
We offer track spirals for H0 and N gauges, precisely tailored to the specific requirements of each railway manufacturer. All track spirals can be installed either left- or right-handed.

How can I bridge large elevation differences with a track helix?
Each track helix requires a so-called base circle. This base circle encompasses the entry and exit of the helix. Any number of extension circles can be placed on top of this base circle, depending on the elevation difference the train is intended to overcome.

The base circle: The base circle comprises 1.5 circles. One base circle provides the overhead clearance as well as the entry and exit.

The extension circle: The extension circle comprises a full circle. Any number of extension circles can be placed on top of one base circle. This allows even the largest height differences to be easily managed in the tightest of spaces.

What does the LAGGIES track spiral consist of?
The kit includes precisely milled track segments made of 4 mm thick plywood and cleverly designed stands and brackets.
