What is on this site...

On this site you will find a few published (but little known) works that that haven't seen the light of day in formal print. These may or may not have been updated, so please just take them 'as is'.

You will also find some articles or books that have been started but remain incomplete; again, to be taken 'as is'. There is also some information about various books of mine, plus additions and corrections.

Please regard all this very much as 'Work in Progress'; it is all liable to frequent adjustment and updating.

You are welcome to view the documents and provided you acknowledge the source you may use the information in accordance with normal copyright conditions. The documents themselves may not be printed or downloaded.

Mike Horne's Blog Updated 16 November
The station ticket office at Rayners Lane has just closed, after 99 years of operation. This item reviews the station history, what the closure programme is all about and why there are doubts about how this will deliver an improved service to passengers.

Mike Horne's Blog Updated 3 August
At last there is news of the new signalling that is to be installed on the Metropolitan, District, Hammersmith & City and Circle Lines. It is probably good news that it is to be a variant on a system already installed on the Underground, but it is much less good news that it is going to take much longer to install than had been hoped and is going to be a lot more expensive. This is now the third attempt to resignal these lines and some observations are made about why things went wrong and whether we are actually much worse off than we would have been if the original plan had been stuck to.

Mike Horne's Blog Recent Updates (March-June)
Distracted by other things, I have failed to update my blog index recently and need to add the following items:
Scotland Yard 'refurbishment' a bit more than decorating.
New Bus for London, some further observations
The Establishment - a thought-provoking new-ish book
No new signalling on the Circle Line for now, and no 4-minute service either.

What's the photo?

It is the roof of the new part of King's Cross station. I quite like it. Let's face it, it has to be better than the squalid 1970's concourse area...

Related resources?

There is the inevitable blog, which I try and keep topical but it get refreshed in fits and starts. It may be found here: Mike Horne Blog; this will open a new web page, or at least a new tab. Items currently topical, as well as the archive, are listed on my 'other stuff' pages. I can also be found at @machorne.

Many files are in pdf format...

So you will need a pdf reader. If you do not have a pdf reader on your computer, you will need Acrobat (or another PDF) Reader in order to view them. You can download a free reader from Adobe. When reading the files use Page Up and Page Down for navigation.

I am aware that some Firefox users may have a problem with accurately resolving images in pdf files owing to a bug with Firefox's dedicated pdf viewer. It is to be hoped this will be fixed shortly. Firefox can be configured to open pdfs using Adobe reader if the bug becomes intolerable, but it isn't something that relates particularly to pdfs from this site.

Why Metadyne?

The metadyne is an intriguing type of electrical machine, akin to a rotating amplifier, and is particularly suited to heavy duty operation where constant voltage input needs to be converted into a constant current (but adjustable) output. The contrived name comes from the greek 'dynamis', meaning power. The machine had was found to be useful for certain types of drive mechanism, including gun turrets and cranes, and to a lesser extent, traction; under this name it was developed in the 1930s and 40s by Metropolitan Vickers and was a development of the earlier Amplidyne machine developed in America.

Whilst there are all kinds of stories I could offer you as to why it is relevant to this site, actually I was after a fairly ambiguous name and just liked it!
