A nationwide search is under way for 10 young women who travelled with the Flying Scotsman to the US 36 years ago.
Setting out for the big adventure - selling the UK to the US in 1969
York's National Railway Museum wants to reunite them as it launches a new display of the iconic steam engine.
The group accompanied the engine - and a couple of Routemaster London buses - on a road tour of the US in 1969, publicising the best of British goods.
They would now be in their 50s and 60s and their whereabouts are unknown. The museum bought the engine in 2004.
Joe Savage, Exhibition Developer at the Museum, commented: "You have to remember that despite it being the 'swinging 60s', it was still relatively unheard of for young girls to travel abroad, and they were probably away from home for the first time.
"Not only that, but it was also a unique excursion for anyone to have experienced. Unfortunately as it currently stands we can only imagine the exciting adventures they had!
"We are very keen to find out more about these ladies and really hope they or their friends or relatives will come forward to tell their unheard stories."
