What forces does the 2D train model use?

The same traction, aerodynamic drag and gradient-resistance equations as the 3D cab: motor traction falls off at high speed, drag grows with the square of speed, and track gradient adds or removes load depending on the sign of the grade.

What does AFB cruise control do?

AFB automatically drives the power/brake controller to hold the train at the target speed you set on the slider, the same closed-loop behaviour as the 3D driver's cab.

Why does the speed limit change during the run?

The route has curve and station-approach zones at fixed distances; the line-speed sign and hint text update automatically as the train's cumulative distance travelled crosses each zone boundary.

High-Speed Train Simulator (2D)

A side-view cab drive of the same Aeroline traction/braking/drag physics as the 3D version — work the power-brake controller or hand off to AFB cruise control and watch the line-speed limit change as you pass each curve and the station approach.

This 2D companion runs the same traction, aerodynamic-drag and gradient-resistance equations as the 3D Aeroline cab through a plain side-view canvas: a power/brake controller (or the AFB cruise-control loop, driven toward a target speed you set) determines motor traction and braking force, which are balanced against speed-squared drag and the current track gradient to produce acceleration, while curve and station-approach zones further down the route automatically lower the enforced line-speed limit as you get closer to Geneva.
