1925 It wasn't always a CP vessel. Before that, it was a Cunard ship.

Before that, it was a US troop ship. Before that:

When the keel was laid down as "Ship #264," this vessel was intended to be named the SS Europa; she was to have been a sister ship to the SS Amerika which was being built by Harland and Wolff in Belfast during the same period. At the time of her launching on 29 August 1905, her only peer in size was the slightly smaller Amerika which had been launched days earlier.

Surendered to Britain after the war; then the Yanks had it; then it returned to passenger service.

In 1926, Empress was refitted again, this time with accommodations for first-class, second-class, tourist-class, and third-class passengers. In 1927, another refit resulted in first-class, tourist-class, and third-class accommodations.

On 11 October 1930, Empress of Scotland made her last voyage from Southampton to Cherbourg and Quebec.

When the new Empress of Britain came into service, Empress of Scotland was sold for scrap. She was gutted by a fire at the shipbreakers yard at Blyth on 10 December 1930. She broke in two and sank. Later the breaker's yard raised the pieces, the full scrapping of the hulks was completed by 1933.

The same sad end seems to fall most of them.
