Interlocking Table File Specification

It's Free!

An Interlocking Table File (ITF) is a text-based computer file that defines mechanical interlocking.

You may download the ITF specification here.

Within its manufacturing limitations, MODRATEC can implement the interlocking defined in an ITF as an Interlocking Lever Frame Kit. The behaviour represented by an ITF may be simulated using our SigScribe4 design software (version 1.1.11 or later).

MODRATEC has developed a textual coding language as a means of defining mechanical interlocking as applied to railway interlocking machines. This is preparatory to the release of SigScribe10 and will be applicable to SigScribe4 as at version 1.1.11.

The current version of the ITF Specification is 1.1 dated 20 November 2009.
