How do I change HUD settings in Train Simulator Classic?

To change the HUD in Train Simulator Classic, load a scenario and press F4 to show or hide the main driving HUD. Press F5 repeatedly to cycle the separate driver-information display. Other function keys control labels and task panels; there is no single menu containing every HUD option.

How do I show, hide or simplify the HUD?

Use F4 during a loaded run to control the main driving overlay.

1. Load a scenario or Quick Drive: HUD commands work in the driving view, not on the main menu.
2. Press F4: this shows or hides the main overlay containing the speedometer, reverser, power and brake controls, plus route information where supported.
3. Collapse individual sections: if the displayed HUD has small collapse controls, use them to reduce individual panels without hiding everything.
4. Press F5 repeatedly: this cycles the technical driver-information display through its available levels and eventually back to off.

Beginners may find our first-run explanation of the driving display useful before attempting a scenario without the HUD.

Which keys control each HUD display?

Train Simulator Classic divides its on-screen information between several independent overlays.

These overlays can be combined. For example, you can hide the large F4 interface while retaining F5 data or platform labels. Our complete Train Simulator Classic keyboard reference covers the remaining camera, map and driving commands.

Can I resize or customise the Train Simulator Classic HUD?

The standard HUD cannot normally be freely dragged, recoloured or resized independently through the game's options.

You can choose which overlays are visible and collapse supported panels, but the interface's apparent size is tied largely to display resolution and scaling. If it is uncomfortably small on a high-resolution monitor, use any interface-scaling option exposed by your installation first; otherwise, a lower in-game resolution makes the HUD larger at the cost of image sharpness. Our display-resolution and graphics guidance explains the wider trade-offs.

HUD visibility may also reset when another scenario is loaded, so do not assume every overlay choice is stored permanently.

Does hiding the HUD change the train controls?

Hiding the HUD removes the overlay but does not disable keyboard commands or clickable cab controls.

You will lose the HUD's mouse-operated levers, so learn the relevant keyboard commands or drive directly from the cab before switching it off. The basic driving controls and braking sequence provide a practical reference.

Advanced scripted locomotives are a common gotcha: their custom safety systems, power selectors or brake controls may not be represented accurately by the generic HUD. In that case, use the cab controls and the locomotive's supplied documentation rather than relying solely on the F4 display.

Why is the HUD not changing when I press F4?

If F4 does nothing, the function key is usually being intercepted or the simulator does not have keyboard focus.

• Click once inside the 3D driving view, then press F4 again.
• On a laptop or compact keyboard, try Fn+F4 or change the keyboard's action-key mode so the function row sends standard F-keys.
• Close any menu, text-entry box or overlay that may be capturing keyboard input.
• Check for keyboard utilities or remapping software that has assigned another action to F4.
• If only the text remains, press F5 several times. That display cycles through multiple pages rather than behaving as a simple on/off switch.
