The result was delete. The "keep" opinions, while in the majority, make weak (or no) arguments: there is broad community consensus that all article topics must have substantial coverage in multiple reliable sources (WP:GNG). Only one "keep" opinion even cites a source, and it is not even really about this topic, but about a subtopic ("exchange stations"). Apart from that, nobody else has found any coverage approaching the requirements of WP:GNG. Sandstein 18:27, 1 February 2022 (UTC)
