You can read about it here:
I was off work this day...might have been sick. This was after office hours though, so unlikely I'd have been still at my desk when this started.
I received a text on my phone the next day telling me not to go to the office but to get myself up to Leyton signals depot instead. I'd been there once or twice so getting there wasn't going to be a problem.
initially I had my own office and everything! But as it was clear the new location was to be permanent I as forced to relocate into the main office so the office could be used for something more important.
I ended working at Leyton for about 2 or 3 years...
