During the steam engine period of British Railways all the larger
locomotives were named.
Can anyone point me to a website listing all the names? with if
possible the classes and dates of use.

Hi, kemlo.

I could not find a list of all the British Railways locomotives, but I
did locate a database of the names of Great Western locomotives.

The Great Western Archive
http://www.greatwestern.org.uk/names.htm

You can see the names of locomotives that start with a certain letter
of the alphabet by clicking on the left of the page (for some reason,
the images don't show up in my browser, but by hovering your mouse
over each missing image, it's easy to see which letter is
represented).

I hope someone else can find a more comprehensive list for you.

For a real railway enthusiast, this book might be worth buying:
