It was renumbered back to 4489 following a cosmetic restoration at the National Railway Museum in York during late 2012 and early 2013.

The coat of arms of Canada was on the side of the cab and a CPR-type bell mounted ahead of the single chimney.

This was due to the use of this locomotive and the other A4s named after British Commonwealth countries, on the Coronation service in order to match with the rolling stock.

[2] Dominion of Canada had the Canadian Pacific Railway-type bell and 5-chime whistle removed in 1957 when the engine was refitted with a double chimney and Kylchap exhaust to improve its steaming performance.

Dominion of Canada had eleven boilers throughout its career: 8952 (from new); 8908 (from 2510 Quicksilver), 21 February 1942; 9126 (from 4482 Golden Eagle), 10 May 1946; 9018 (from 19 Bittern), 8 April 1949; 29273 (from 60014 Silver Link), 29 September 1950; 29321 (New build), 27 August 1953; 29323 (from 60014 Silver Link), 17 February 1955; 29312 (from 60018 Sparrow Hawk), 1 June 1956; 29272 (from 60002 Sir Murrough Wilson), 27 December 1957; 29307 (from 60028 Walter K. Whigham), 10 July 1959; and finally 27970 (from 60007 Sir Nigel Gresley), 5 December 1962.

[3] Dominion of Canada had six tenders through its career: 5326 from new, 5328 from 6 December 1937, 5647 from 29 June 1953, 5639 from 9 July 1953, 5328 from 27 August 1953 and lastly 5326 from 15 October 1960.

However, its boiler was discovered to be in poor condition and the engine was instead withdrawn and on 5 July, it was marked in Darlington's records as 'for sale to be scrapped'.

After 60010 was condemned and its double chimney was removed for either 60024 Kingfisher or 60004 William Whitelaw, both in the works at that time, it was placed behind Darlington motive power depot and forgotten.

For many months it was left lying derelict, almost totally hidden in the weeds and rough bushes at the end of a siding from the MPD, nose into the embankment of the Haughton Road bridge in Darlington.

In 2011 the National Railway Museum in York announced that it would be bringing back 60010 (along with fellow A4 Dwight D Eisenhower ) to the UK for a 2-year period to celebrate the 75th anniversary of the record-breaking run of its classmate Mallard.

After arriving back in the UK on the evening of 2 October 2012, both locomotives were unloaded the following morning at Liverpool Docks, where a press call had been arranged.

On 19–20 October 2012, Union of South Africa visited Shildon as well, so that a line up of three Brunswick Green A4s could take place for the first time since the end of Eastern steam in 1966 - it was originally planned to be an earlier event and also feature 60007 Sir Nigel Gresley, but the A4s' shipping date was delayed, so 60007 could not be secured for the date due to commitments at the North Yorkshire Moors Railway.

Both 60008 and 60010 appeared at Barrow Hill roundhouse along with Bittern (60019) as part of the "East Coast Giants" event over the weekend of 8/9 February 2014.

4489 was reunited with her five remaining A4 siblings for the final time at The National Railway Museum's Locomotion facility at Shildon for "The Great Goodbye" held 15–23 February 2014.
