33" - 36" Radius 5.5 Level Helix (Grade 1.5%)

PROSES Modular Helix V3 for Bachmann E-Z Track (33"–36" Radii, 5.5 Levels)

Optimize your model railway layout with the PROSES Modular Helix V3, designed for Bachmann E-Z Track and other popular HO scale track systems with radii between 33" and 36".

This double-track, 5.5-level helix provides substantial elevation gain while maintaining an exceptionally gentle gradient of approximately 1.5%, allowing smoother, more reliable operation and better performance with longer trains.

Key Features

• Modular Design: 5.5 levels with quick and easy assembly

• Bachmann E-Z Track Compatible: Designed for Bachmann E-Z Track curves, including 44504 and 44507

• Versatile Track Compatibility: Suitable for curved tracks with radii from 33" to 36", including flexible track

• Double-Track Layout: Allows separate ascending and descending train movements

• Low Gradient Design: Gentle 1.5% gradient reduces the climbing effort required from locomotives

• Lightweight & Durable: Strong modular construction designed for convenient assembly and installation

Dimensions & Technical Details

• Track Radius: 33"–36" (838–914 mm)

• Center Radius: 34.38" (873 mm)

• Track Bed Width: 7" (17.8 cm)

• Number of Levels: 5.5

• Vertical Distance Between Levels: 3.15" (8 cm)

• Total Height to Climb: 22" (56 cm)

• Overall Width: 77" (196 cm)

Gradient

• Approximate Gradient: 1.5%

The large track radii and gentle gradient help reduce locomotive strain, improve traction, and allow longer trains to climb more smoothly and reliably.

Easy & Flexible Assembly

All PROSES helices can be assembled clockwise or anti-clockwise, allowing:

• Entry or exit from left or right

• Entry or exit from top or bottom

The fully modular construction also makes it easy to disassemble, relocate, or modify the helix when changes to your layout are needed.

Compatibility

Designed for Bachmann E-Z Track, including curved track sections 44504 and 44507.

Also compatible with suitable curved or flexible HO scale tracks from other manufacturers, accommodating radii between 33" and 36".

Please note: Tracks are not included.
