>>1745160>merry christmas, everyone! thanks so much for all your help. i've got 6 wikipedia tabs open right now and i'm sure more are gonna pop up as i dive deeper. really interesting stuff. just learnt about wheel arrangements.Merry christmas to you too! You can really go on some deepdives there, once you start looking into railway companies you just drift off into individual lines, locomotives and accidents. Once you start reading accident reports you may have delved too far!
