Two generations of East Coast Main Line express power at Doncaster on July 3rd 1988. Mallard had just taken over a King's Cross-Scarborough railtour marking the 50th anniversary of her record-breaking run in 1938 and was posed next to a brand-new class 91, showing the East Coast express linage. Photos like this show just how timeless the streamlined shape of the A4 Pacific is.
