This is from infojd.ru. Sergei Bolashenko took down the site after Russian zoomers mocked him online for "racism" against Central Asians. Ironically, some of the most sincere photography of the former Soviet Union that I've ever seen. The guy was a train autist, and had a poorly-organized website with travelogues of him taking every Soviet line he could find still operational, and when not, he would hike along them for documentation purposes. Thousands of photos. These are some of the ones I've saved. Unfortunately, my Russian is less than rudimentary, so I haven't been able to glean much more.
