Silver Link entered service with a demonstration journey departing from King's Cross Station on 27 September 1935. 2509 reached a top speed of 112.5 mph (181.1 km/h), breaking all previous UK records. The record provoked the LNER and their chief rival the London, Midland and Scottish Railway (LMS) into a highly competitive speed war, each attempting to outdo the other by building ever faster locomotives. The main protagonists were Sir Nigel Gresley, LNER's chief mechanical engineer, and his counterpart at LMS, Sir William Stanier.

Naming

Silver Link was named after a reference to love in Sir Walter Scott's poem The Lay of the Last Minstrel, which reads:

The engine was "officially named" (using its real name) in the opening scene of the 1937 comedy film Oh, Mr Porter!.

Scrapping and legacy

Allocated to Kings Cross shed, it was withdrawn from service on 29 December 1962 when the East Coast Main Line express services were taken over by Class 55 'Deltic' diesel locomotives. It was not preserved after withdrawal and was broken up for scrap at Doncaster Works on 7 September 1963, on the same site where it had been built nearly twenty eight years earlier. There was an attempt by Sir Billy Butlin to save the locomotive, but it was unsuccessful.

Two examples of the Silver Link nameplate are on display at the National Railway Museum, York, UK.

The Silverlink area of North Tyneside is named after the locomotive; the name of the area was taken after another A4 locomotive.

Former classmate LNER 4464 Bittern was repainted in 1991 and disguised as 2509 Silver Link. It was moved around on static display in the early to mid 1990s. It was eventually reverted to its real identity as 4464 post 1995 as the locomotive was being dismantled for eventual operation
