Bring back the Stanmore Village branch, and have the only steam-operated heritage railway within Greater London*!
Never going to happen of course, as most of the route is now either a "Green Corridor" footpath or has been built on.
Perhaps Southall-Brentford could become a home for regular steam services at weekends, when it isn't required for freight?
* Edit - forgot about the Museum of Water & Steam at Kew which has its own narrow-gauge steam railway - my bad.
