England's Lost Main Line Railway: Rediscovering the Great Central Main Line

From a channel Lumen includes in full: Every available transcript (Waverley, Busway, Cambridgeshire industrial lines, Great Central, Somerset & Dorset) is a serious, fact-dense narrated documentary on railway history, engineering and closure policy, combining archive film with site surveys. All 31 sampled titles follow the same lost-railway documentary format, with no vlogs, reactions, reviews or promos. A few titles use mild narrative framing (e.g. 'Attacked. Derailed. Blown-up'), but they are descriptive rather than shouty or deceptive.
