TXE6
TXE6 was an electronic common control exchange that was designed to extend Strowger exchanges, and known as the Electronic Reed Selector System or Reed Group Selector (RGS). Only two were built: one in London and the other at Leighton Buzzard. The one in London was moved and combined with the one at Leighton Buzzard (incidentally the Leighton Buzzard one was coloured light straw and the London one grey so when they were combined it was easy to tell where each unit came from).
It was never used for its intended purpose but merely acted as the front end to incoming junction calls at Leighton Buzzard and directing them to the appropriate part of the exchange decided by the first dialled digit. As the name suggests it used reeds as its switching medium.
