To explain my interest in railways I must go back many years.
In 1956 I was living very close to the Kent Coast main line which was in the process of being electrified as part of the 1955 modernisation scheme. What made a lasting impression on me was the section of line between Bickley and Swanley was being quadrupled. This involved massive earthworks and major bridge rebuilding including a five arch viaduct. This was akin to building a motorway on top of an existing road which was still open to traffic.
Not for me was there any interest in collecting engine numbers which I think must be a pretty boring pastime. Instead I developed an interest in the reason why railway lines were built where they were and the impact on the community and also the politics behind them. For instance in Kent there were two major railway companies the South Eastern and the London, Chatham and Dover who were in fierce competition with each other and led to many duplicated routes, even to this day there are 12 routes between London and Dover but try and get from Faversham to Tonbridge is a complicated journey to say the least!
I hope this makes sense and I hope it will help you understand future memories.
