| It's fair enough that the London & North Eastern Railway's East Coast Mainline was the Mallard's main route, but here it is on the modern, electrified Network Rail ECML in 2003!!! Admittedly, it wasn't under steam, as it had a boiler fault at the time, and was being deadheaded by ex-LNER #4771 "Green Arrow" to the Doncaster 150 Celebration. |
