A friend of mine who is older than me and used to spot in the late 50s early 60s talks about 'the field' at Tamworth, and going there to spot. He speaks as if this field was leased / provided by BR for spotters in order to clear them off the station to a location where they may be less nuisance to other passengers or to stop crowds of kids building up (this may of course be his childhood assumption about it as he admits, you don't tend to wonder about such reasons too much when you are a child I guess). Of course it could simply be that there was a field with easy access and staff told people to use it, and whoever owned it had no issues.
I'm not sure if this was combined with any sort of unwelcoming attitude on the part of staff at Tamworth or not.
On passing through Tamworth on the train I've looked out to wonder which field this was. I'm guessing some people on this forum will be well familiar with it and can give me a clue / map reference?
The field is now a chalet site, in the south-east quadrant of the railway lines.
