Service

Above all though the A1s were renowned for their reliability. By 1961 the class had accumulated 48000000 miles (77,248,320 km), equivalent to 202 miles (325.1 km) per locomotive each calendar day. These were unmatched by any other steam locomotive on British Railways. Some of the best performances were put in by Nos 60153-57, which in a move to increase distance between general repairs were fitted with roller bearing axleboxes. Between 1949 and 1961 this quintet totalled 4800000 miles (7,724,832 km) with an average distance between works overhauls of 120,000. In a single year No 60156 Great Central of Kings Cross ran 96000 miles (154,496.6 km).

If there was one drawback to the Peppercorn A1 it was its riding. There were wide variations between individual class members with some very rough indeed. The cause apart from the inevitable axlebox wear lay in the leading bogie

A bogie is a wheeled wagon or trolley. In mechanics terms, a bogie is a chassis or framework carrying wheels, attached to a vehicle. It can be fixed in place, as on a cargo truck, mounted on a swivel, as on a railway carriage/car or locomotive, or sprung as in the suspension of a caterpillar...

 but no adjustments were made at the design stage to tailor it for the heavier A1. Changes to the loading of the bogie side control springs usually brought the riding up to a level comparable with other express types.

Withdrawal

By summer of 1966 all 49 class members had gone for scrap. The last to be withdrawn from stock was No. 60145 Saint Mungo after a working life of just 17 years. An attempt to save the locomotive for preservation came to naught.
