No. 4472 Flying Scotsman headed the northbound inaugural non-stop ‘Flying Scotsman’ from King’s Cross on 1 May 1928 and No. 2580 Shotover the southbound from Waverley. The non-stop journey of 392 miles was only possible because of the 10 corridor tenders originally fitted to selected class A1/A3 locomotives. Four more were built for the class A4s and all were subsequently transfered to them.

The photograph above shows No. 4472 when first fitted with the corridor tender and the one below shows Flying Scotsman prior to the departure of the first train with Sir Charles Batho (The Lord Mayor of London) and HN Gresley in the cab, accompanied by Driver Pibworth.
