This YouTube channel showed up under my suggestions area of YT. I thought it was interesting, different, and don't know a lot about the European type railroads. Neither the companies and such that were/are closing. She built a Monochrome layout which as a fan of Black & White moves I thought was interesting. Appears to be fairly new? https://www.youtube.com/@modelrailwayquest/featured
British, I see. Nice YouTube site with lots of info, and well presented videos. Seems to have weekly updates and last post (as of this post) was 4 hours ago.
