How about sending them to Northfields? There are 4 tracks between Acton
Town and Northfields, so it shouldn't affect the Piccadilly too much.

Isn't one of these a test track?


Not any more - it was recommissioned for normal passenger train use in 1995, though, for operational convenience at Acton Town, almost all eastbound trains use the fast line.
