I started as a trainee Electrical Engineer in 1978 with the MEB and was based at the Summer Lane offices but did much of my training at either the Southern District, in Kings Heath, or the Eastern District, in Solihull. Very occasionally, they would send me across the city to the Northern District, in Erdington.
There was a training centre at the rear of the Summer Lane offices, to get to it you had to pass by the computer room and cross an enclosed bridge. There was a cafe enclosed into part of the building and the smell of burnt toast would often trigger my migraine. I also remember a notice that read something like "Anyone found not replacing the test equipment will be pressure tested". A pressure test on a high voltage cable involved applying a high voltage, at low current, to test that the insulation on the conductors would hold when the supply was switched back on after working on a cable.
There was a Sports and Social Club in Henrietta Street, which we would often go to for the lunch break on a Friday if on a course at the training centre. Back in the days when you would be allowed to do such a thing...
