Integrated Electronic Control Centre

ARS can also handle severely disrupted service patterns and assist the signaller in the event of train or infrastructure failures.

IECCs were developed as an alternative to the traditional switch or button panel control, which in turn replaced mechanical lever frames.

The solution used off-the-shelf microcomputer technology (Motorola 68000 microprocessors and VME Bus) to host the sub-systems of IECC in high availability configurations linked via a duplicated Nine Tiles Superlink local area network.

Following a successful six-month trial at Swindon B in 2012, IECC Scalable is now the standard for new installations, starting with Cambridge where it controls the Ely-Norwich line which has been resignalled on the "modular signalling" concept for secondary routes.

They are VDU based signalling control systems with a similar "look and feel" but in most cases they do not incorporate Automatic Route Setting.
