Modified in 1980, "Pendennis Castle" was used for various other excursion trains on the company's ore-carrying railways. After further modifications, she was moved by road to Perth, where she had a historic reunion with "Flying Scotsman" on 17 September 1989. During the 1990s, after various difficulties and with the expiry of the boiler certificate, she made her final run on 14 October 1994. Hamersley Iron were not prepared to pay a repair bill of 240,000 Australian Dollars, and repairs were becoming uneconomical after fully electronic signalling was installed, which would have required the locomotive to run behind a GE Transportation Systems Dash 9. This resulted in the locomotive being stored for several years.
