What can TERN do?

It can control multiple train movements on simple rail layouts so increasing line capacity and, potentially, revenue.

It can be a low-cost control option for railways that are planning to extend their layouts but for whom conventional signalling would be too costly or impractical.

It can even:

- Lock out a ground frame by the physical capture of an Annetts key.

 - Substitute for a physical link between conventional key token machines. 

 - Be a portable control system for railways that have only the occasional need  for complex movements.
