Looking back through my recently rediscovered notebooks, I see that I conducted an eleven hour survey of loco-hauled services and light engine movements stopping at, or passing through, Darlington on Thursday 1st August 1974, from 09 00 to 20 00. That would have been a marathon session for a one hour platform ticket, priced at 2p, although, as I was staying with my maternal grandparents near Eaglescliffe, I would have almost certainly arrived and departed by train....and therefore would have been in possession of a valid travel ticket. At first I thought of posting this under the 'Back in The Day' thread but, given the size of the document and the fact that I'm already in danger of going widely off-topic date-wise, I decided that it would be best to make it a new thread. It's amazing to see how much the railway has changed in the intervening 47 years....so much more freight traffic then and far fewer long distance passenger trains. Please feel free to correct my teenage observations and fill-in the missing headcodes and destinations if you can.
