British Rail Research was bought by AEA Technology Rail, who took over the supply of new IECCs, support for the existing installed base, and enhancements to the hardware and software. In 2006, the AEA rail business became DeltaRail (now called Resonate Group), who have developed IECC Scalable which replicates all the functionality of the original IECC on a modern hardware platform and software architecture. 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. List of IECCs in service as of 1 January 2017 The following installations are not true IECCs of the BR/SEMA/DeltaRail design. They are VDU based signalling control systems with a similar "look and feel" but in most cases they do not incorporate Automatic Route Setting. Some locations shown below are interim installations which will eventually move into larger signalling control centres, such as Leamington and Madeley, which in time will move to the West Midlands Signalling Centre.
