Sending the right signals?
Lever Frames by MODRATEC

A 12-lever example of a MODRATEC Mechanically Interlocked Lever Frame. This frame has additional electrical releases on levers 4, 7 and 10.

MODRATEC has developed a system that allows virtually any railway modeller to incorporate what they have always dreamed of—realistic hands-on control of points and signals, interlocked for safety.

And even if you don't have a model railway, a fully interlocked Lever Frame makes a great executive toy!


Each MODRATEC Mechanically Interlocked Lever Frame is customised for your specific layout requirements.


Your design

... the task of making a proper frame, with tappets and sliders working in concert to prevent a conflicting move or unsafe working method being executed, has been made considerably easier thanks to MODRATEC of Australia. [RAILWAY MODELLER - Feb 2006]

Interlocking design has always seemed something of a mysterious black art. To overcome this, MODRATEC has created a design tool called SigScribe4.

You can download SigScribe4 free of charge. You use it to draw your track plan, place signals, and define routes. SigScribe4 then creates the mechanical interlocking design and simulates it so that you can test your design.

Your Lever Frame Kit

MODRATEC uses your SigScribe4 design to generate your customised Kit and Construction Manual.

Kit construction involves the application of basic workshop skills and tools. All parts are pre-drilled and tapped as required. The builder is required to file notches in interlocking tappets according to details tabulated in the Construction Manual.
