Now I know how mere mortals must feel when computer types have geeky
conversations in the pub.

Thanks for that erudite response, Huge.

Having read the discussions in the NG about topics such as signalling ground
frames, which were not flamed as being 'geeky', there was I thinking that
this was a forum for discussing topics related to transport in London.

If bus blinds arer't your thing, Huge, why not show some tolerance and
refrain from ****ing on someone else's bonfine?
