It's possible to drive past almost all of these sites without suspecting anything, so this section of the site exists to allow as much information as possible to be collected on various once-planned services, such as where they are, what they would have been like, why they didn't go ahead and what they're like now. They have all been planned in detail at one point or another, it's just that those plans are very hard to track down!
There are a few extra unbuilt services which we know very little about, these can be found on Other Unbuilt Services. The rest of them are listed below, you can click on each link for more information. You can also view this information on a map.
