Debugmode – Test mode, allows for more accurate testing. At the top of the screen (red text) the driven vehicle parameters are shown. In this mode, all failures are disabled (ie. derailing), CA / DSD (Driver Safety Device, not acknowledging "SHP") does not cause emergency braking. In the logfile, extra information about train movements and activated events is saved, this is to help with the debugging of the scenarios. In debugmode, opposite to the normal mode, certain keys have the following functions:

• Ctrl+Shift+F12 – Switch between the debugmode and normal modes.
• F1 – With Shift Moves the clock by 5min, with Ctrl by 20min.
• F6 – Speed up the whole simulation (Speed up the simulation's calculations, with Shift - 2x, Ctrl - 5x, Shift+Ctrl - 10x); May cause problems with event activation, especially when the FPS drops below 20FPS.
• Esc – Speed up the simulation of the physics only (might cause problems with launching certain events);
• F7 – Show the mesh wire-frame / node triangles, does not work correctly;
• Ctrl + F7 – Change between light calculated from current time, and constant day light
• [ and ] keys – Shift the driven vehicle 100 meters to the front / back;
• q – Deactivate the AI autopilot (after enabling it).

Turning on the AI (Shift + q) does not lock the keyboard. Also, the inside cab boundaries are gone.
Catenary wire color coding:

Blue / Yellow – Fed from single side (depends on the direction)

Green – Bidirectional feeding

Red – Sections connected to other isolated sections, or section fed from single side

White – Connected directly to the power source (Transformator)

Black – No power

This mode should normally NOT be used in the simulator.
