This article is about the human character. You may be looking for the boat.
Nancy Rushen is a guard's daughter who lived near the Skarloey Railway and occasionally polished the engines.
On one occasion she was polishing Skarloey for Rheneas' return and Duncan became extremely jealous after she had no time to clean him, as she was scheduled to help the Refreshment Lady. She later appeared in Very Old Engines polishing Skarloey for his centenary. After he became cross and she called him a "crosspatch", Skarloey told her the story of his first days on the railway and the time he really was a crosspatch.
In the Railway Series, she has grown up and lives with her husband on the Isle of Man.
