@infrastructureiq: These railway rails look vertical. They aren't. 🚆 On Network Rail plain line, the nominal rail inclination is 1 in 20 — only around 2.9°. That tiny angle forms part of the carefully engineered geometry between wheel and rail. And not every rail is inclined... Some track designs deliberately use vertical rail too. They're not crooked. They're engineered. #InfrastructureIQ #RailEngineering #Railways #STEMTok #TrainTok
