Platform screen doors (PSD)

What PSDs are

Platform screen doors (PSD) are the glass screens between platform and track. They close the gap and only open where a train door is. They are at every L2, L3 and L11 station in the simulator.

If you stop badly, platform leaves and train doors do not line up and people cannot cross cleanly. That is why the game helps with the stop bar.

The HUD stop bar

As you near a PSD platform (within about 240 m), to the left of the track strip a vertical gauge appears: red arrows top and bottom, a striped band in the middle and a moving black line.

The black line is your position relative to the door stop mark. You want it inside the striped band when you stop.

• “Platform door stop mark” / “You are short”: you still need distance. Creep forward.
• “Within the margin”: good. The red arrows fade. You can open.
• “You overshot”: past the mark. If the train allows, ease back.

Open and close with the train

With the train stopped at the platform, O and P open the train doors (correct side). In PSD automatic mode, the platform screens open by themselves when the train requests open and is stopped at that platform.

Before closing, press T (chime). Then close the train. The PSDs follow the train: if you close, they close too (unless they are in manual or a leaf is out of service).

• While any screen (or the track-access door) is still open, the train cannot leave — you get a platform-door hold.
• After everything is fully closed, there are about 2 seconds of departure wait before the PSD hold clears.
• If someone (including you) stands in the screen gap, it will not close — you get a move-aside warning. The train will not leave until it closes.

ATO vs ATP

In ATO (key 2, hold Space to start) the braking profile aims at the door mark. When you are already very slow, the system settles on that point. The HUD bar still shows how you arrive.

In ATP or M+25 the mark does not move the train — you brake. Start early, arrive at walking pace and watch the black line enter the striped band.

Platform cabinet (AAC and driver)

At the head of each platform there is a PSD control cabinet. Use it when the screens fail (not opening, not closing or stuck halfway). Customer Service Agents (AAC) use it, and so can the driver if the doors must be run by hand.

The cabinet asks for the platform password. The driver requests it by calling the CCM from the cab phone (or from the platform intercom). Once the CCM gives it, unlock the cabinet, switch to Manual, open or close all or one leaf, and return to Automatic when the fault is cleared. If left in manual, the next train will not move the screens on its own.

• Normal use: Automatic. The PSDs follow the train without touching the cabinet.
• AAC or driver: only if the screens fail or a leaf must be isolated.
• Driver: ask the CCM for the password by phone before opening the cabinet.
• An out-of-service leaf will not open with the train; from inside the train a passenger can still open it by hand with the handle if needed.

Track access (exceptional cases)

On L2 and L3, next to the passenger screens, a service door leads to the track. It asks for a different password (not the AAC cabinet one). Use it only in exceptional cases: track incident, controlled evacuation or a one-off job with service stopped or held.

If you open it, the train at that platform is held (“Track-access door open”) until it closes. It is not a passenger shortcut or a normal way to cross.

Summary

As a driver: hit the mark with the bar, open and close the train, and the PSDs follow. If they fail, ask the CCM for the password and run them from the cabinet (an AAC can do it too). Track access only in exceptional cases.
