GALLERY: Steam enthusiasts share their photos of Tornado
These images, taken from social media, show the buzz created by steam locomotive Tornado's arrival in Yorkshire. The engine hauled the first timetabled steam services on the British network since the 1960s.
Huge crowds gathered to see it run between Skipton and Appleby on Tuesday, Wednesday and Thursday this week. Many of the Northern services were a sell-out, with large queues for unreserved tickets on the day.
