While slowly going through the Wikidata SPARQL query examples of last year<\/a> I ran across this one<\/a> which draws the shortest railway link between Narvik, Norway, and Singapore. Amazing, really. What was also interesting to find out that still in October 2021, the route went via Sweden<\/a>. I’m not that inclined in train networks but AFAIK the opening of Lule\u00e5-Haparanda track in the beginning of April 2021 changed this route also in Wikidata, eventually. <\/p>\n\n\n\n

The news came from a tweet<\/a> by James Benedict Brown, Associate Professor of Architecture at Ume\u00e5 University. His travel stories are nice reading. For example, here is a thread<\/a> on how he and his students traveled in Finland at ground level in summer 2022. Recently, he announced <\/a>in Mastodon, that early next spring, the target will be Athens. Having the above-mentioned SPARQL query at hand, I asked Wikidata to draw me the shortest route from Ume\u00e5 to Athens.<\/p>\n\n\n\n

The return was 0. Wikidata does not know about a consecutive line of adjacent railway stations between these two cities. How far, in the direction of Athens, does it know these stations then? Inside the borders of Greece , one of the last stations with a clear, labelled indication of a preceding station is Didymoteicho<\/a> near the Turkish border. From that station on towards Athens, the route quickly stagnates. You can run the query here<\/a> Click the big Run\/Play button. The query takes a few seconds to complete. <\/p>\n\n\n\n

(I couldn’t help choosing the title, thank you Bowie<\/a>.)
