However, the subject matter need not exclusively be about London Underground, as long as there is a substantial amount of relevant content. For example, the website might be about railways in general, with a particular section about the tube. In such cases, deep linking (where the URL suggested points to a page other than the main home page) may be appropriate.
Some websites might not be suitable for inclusion in this category because their content is not relevant, or there is too little compared to the main subject, even if the title includes “London Underground,” “Tube,” or similar phrases. For example, London travel guides, or websites promoting London tourist attractions, restaurants and clubs etc, plotting their locations in relation to London Underground stations, would not normally be suitable for inclusion here. Instead, they should be submitted under Regional: Europe: United Kingdom: England: London: Guides and Directories. Websites promoting London Underground merchandise and memorabilia (as their primary function) should be submitted to the relevant category under Shopping.
Weblogs about London Underground have their own category at Regional: Europe: United Kingdom: England: London: Transport: Underground: Weblogs, and should be submitted there.
