🚂 Diesel-Electric Locomotive Lab: Tractive Effort, Wheel Adhesion, Train Resistance and Braking

Drive a generic six-axle diesel-electric freight locomotive with civil freight wagons and see why it pulls, slips and stops: the tractive-effort curve F = min(μW, ηP/v), the wheel creep curve with slip control and sand, Davis train resistance on grades and curves, air-brake pressure waves, slack action and wheelset hunting. Unlike the railway traffic and high-speed rail simulations, this lab models locomotive traction, adhesion and train-brake dynamics with measured-versus-predicted checks.
