That is an amazing photograph and event. It looks to me like their only move was a 180deg. turn? Thank you for sharing and the compliment!
I had two railroad experiences in England several decades ago: First, a trip from London to Henley-on-Thames to visit the model steam engine maker "Stuart Models"; and second traveling with 80+ people on a Sunday morning as a guest on a company sponsored charter of an entire train pulled by a steam engine with all dining cars set up for breakfast with proper white table cloths, etc. from Victoria Station to Edinburgh, Scotland via York. It was First Class in every possible way. Happy New Year.
