With flight search engines, it is possible to search for routes excluding particular airports. Is there an equivalent way to search train routse excluding particular stations/cities? For example, one might search for connections between two French cities avoiding connections through Paris. Does any search engine with such a functionality exist?
I am particularly interested in Europe, i.e. the area covered by HAFAS when searching through Bahn.de, SBB, B-rail, NS Internationaal, etc. I noticed those search engines all use the same database, but are a bit different in their additional search options.
