Hello skyhunter66 and welcome to the forum. An excellent website exists at
http://www.uksteam.info which lists all steam workings in Britain and will usually have times added about 4 or 5 days prior to each run taking place. Please bear in mind that it's all unofficial and can only show what's been supplied, if no one supplies the website owner with times he can't post 'em. As to where to stand? I would not like to make a guess, I have been on York station when steam has been running and the crowd was huge! Four deep along platform three. It's a case of if you see a gap, fill it.
