🚆 Branch Line Journey: Traction, Gradients, Signal Blocks and Timetable Lab

Drive a steam or diesel-electric train along a fictional three-station branch line: power lever, air brake with its 3 s delay, 1-in-100 and 1-in-60 gradients, wet-rail adhesion, three-aspect signal blocks, and a time-distance (Marey) planner for two trains. Real Davis resistance, adhesion and braking-distance equations with five independent numerical checks.
