I remember seeing the Flying Scotsman when she arrived in Boston. I was 7 at the time and sadly didn't take pictures. Who does at that age!

Here's a film clip of the tour - brief bit of it anyway, with some footage in the New York and Philadelphia area where she passes a United Aircraft Turbo Train and some Metroliners.
After I saw her in person, I set about drawing British and European trains. I used to draw trains all the time as a kid, filling up paper with yard diagrams, maps, and side pictures. I was very fascinated with railroads growing up, and I suppose I still am!

The main features I remember were the buffers, short stack and red pilot. For me there was both a fascination because she was different, yet there is that real beauty found in British locomotives that makes them stand so far apart from the US/Canadian as well as their European counterparts.
If only I could go back in time and visit the UK before British Rail and Beeching had ruined everything just like things were happening at the same time over here in the US. Gone now of course are my favorites PRR, NYC, NH, BM, MEC, CV, and... fill in all the fallen flags that made a boy who loved trains day dream about them.
