Correct on all counts. I'm impressed. They were spread around a whole lot of lines - where is "the office"?
What an immense feeling of satisfaction, only hampered by the sad realisation that I must have spent far too much time on trains in the course of business and leisure. Indeed, only this morning I enjoyed a two way reversal at Newbury because of a points failure, followed by half an hour taking in the scenery at Theale while the traincrew sorted out a dodgy train door. It's very easy to gain a photographic memory of stations in these circumstances!
The office is in central London, by the way. Better go now, the boss is watching
