Stations, ahh, stations. During various lonely and frustrated periods of my childhood, starting about 12, I used to bunk off school and hang about on stations. Usually buying an off peak ticket that would take me as far as I could go on my dinner money, or sometimes, having successfully flogged off some singles (vinyl) I'd get to the London stations for a day. Eventually I learned that various trips could be undertaken without tickets at all, e.g. Prittlewell to Paddington or Finsbury Park, changing on to the underground at Stratford. Once you got down on the underground you could go where you liked if you didn't actually want to leave the system, though it wasn't wise to go too far out of the centrer in case you were noticed on a relatively empty train. I'd head back for about normal getting home from school time. The parents never knew. Nor did the school, they were used to me having time off for my eye condition so I guess weren't as concerned as if anyone else had gone missing for a day - or maybe they were glad to be rid of me
In the 70's no-one took the slightest notice of a kid on a busy station, and I delved into all sorts of odd corners that could well spark off thoughts of timeslips - platform 17 at Kings Cross for example, now long gone - it was a wooden excursion platform by the headshunt for the loco yard. There was a signalbox under St Pancras station too, and various odd semi-disused parts of Paddington - the latter all now in full use. Blackfriars was another station virtually moribund outside of rush hours back then .
For whatever reason I used to feel very secure and consoled on those excursions, I think because stations are part of another world with much more clearly defined rules than the real world with which I was struggling. But maybe because of that 'thin' feeling mentioned above - that you were near to something that told you something about the universe. Whatever, such a trip would build me up for another few days of school.
Then about 16 I discovered pubs.
Sorry to ramble on - I'm trying to describe something I always felt was special about stations, especially the big London ones that retained a lot of their Victorian identity, and I realise I haven't got the words.
