Ooops!

The file at www.squarewheels.org.uk which your browser tried to fetch does not exist.

If this is because there is a broken link within this website, then please send me email.

In other cases please first follow the links below to try and find that for which you were looking.

https://www.squarewheels.org.uk/
is the definitive index page for all parts of the website, so all current content is linked from there.
You may also find the site map useful.

Metropolitan Line Train Operators: The Harrow Duty Books are unlinked: you have to type in the correct address, which is printed in the books themselves.

In the course of maintaining this website, some renaming and reorganization of directories is hard to avoid. However this should happen gracefully, i.e. without resulting in “404 Not Found” errors. Where specific files get renamed, I’m using “301 Permanent Redirection” (except from old URLs not hosted on my server), and should items be removed and not replaced, the “410 Gone” http error is used.
