I am pleased to say that at long last, the problems affecting shipping rates seem to have been resolved and with a new and quicker payment system. I have resisted adding new books onto the site until it was fixed so for the time being the newest releases will still only be available on www.railwaybooks.org . I will migrate the lastest books across.
I would value feedback on the new site whether good or bad via the contact form.
Most new books are POST FREE within the UK
