Scandinavian Collectors Club website contains "links to Adobe PDF files, separated into sections for faster downloading. The sections range from 1 to 4 MB in size."
I don't know on what basis or for how long this will be available - I would have expected it to be a member download, but it is currently visible to all.
It's an update on the 1964 book and its style is very much 1960s or even 1910s in that the text appears to be letterpress. Nonetheless it is downloadable and can be saved on tablet devices such as the iPad in the 'Books' app.
Some pages appear to be sheets from the writers album, but the illustrations are in colour, and include early sepia postcards of some stations etc.
