Not a scary train ride but I was about 12yr old, I'd had a day on the rails with my Dad, He wasn't obsessed but for my sake showed a passing interest in Railways, credit to him though, he knew the different classes of loco's that were around, I think we'd been to York n Donnie and got back to Newcastle about 10pm. Despite being on a train for yonks, my Dad decided he'd go to the now long gone loos that were on platform 8 then(Platform 2) now before we went for our bus home. I'd wandered over by the big destination boards, where boots n costa and that are now, to see if anything was due in, whilst waiting for him, a guy strode up and asked, if I would go on the metro to Whitley Bay with him? saying he would pay me, as he didn't know the way. I just said, no, I'm waiting for my Dad and here he is now, pointing at him, as my Dad was now striding towards me and the guy took off. My Dad dragged me down the metro stairs to find him but we couldn't see him. We then went and found a police man, who was stood outside Central Station and I had to give a statement.
Never been as scared as that night, mind you my Dad got a bigger fright and my stepmother got one too, when Dad n I got out the police car outside the house, ofcourse, my Dad got a canning off her about leaving me.
