About the how fast they close, they're pneumatic, so this is a piston, pressure one one side pulling the doors open, on the other to close them, when doors are open, you have a little button to 'prepare closure', which release pressure on the "open side", so when you close them, there is less air to empty and they're closing faster.
This system is used on the Mexico City Metro and Santiago Metro to a extent. In the cab there are 2 buttons on the side of the drivers doors. One of them, just like you said 'prepares closure' and triggers the BEEP to the passengers. The buttons are on these sides, because the driver needs to look at the platform in case someone (or something) gets stuck on the doors.
The funny thing is that Santiago Metro also uses the door closing button as a little dead man's switch, meaning that after the doors closes and the train departs, the driver has to keep pressing the button for a few seconds. Fortunately, there are other buttons to close the doors on the NS-74, just to the right side of the panel.
On both trains there are a pair of switches that on the document above only mentions them as "Comnutador C" and "Conmutador T1".
Conmutador C enables 3 different driving modes:
- PA: "Pilotaje Automático", or Automatic Pilot (like AI trains).
- CMC: "Conducción Manual Controlada", or Controlled Manual Mode (normal driving mode, with safety systems in place, just like any train in the simulator).
- CML: "Conducción Manual Libre", or Free Manual Mode (normal driving mode, but disables any safety systems, used on shunting and on emergency situations).
Conmutador T1 changes the door opening side: left, right, or both at the same time.
You may also noted the small sign at the front of the NS-74, saying
Ruta Verde and
Ruta Roja. Santiago Metro, until the arrival of the AS-02 on Line 4 (2004), and the arrival of the NS-07 on Line 1 (2009), didn't used destination signs at all!
When the Express System debuted on Line 4 (2007) and later on Line 5 (2008) and Line 2 (2009), these signs and LED lights on the sides of the trains were retrofitted to help people differentiate both routes, as Chileans weren't used to trains going different places (or different stops) as there are no branchlines or short services on the system. The Express System only works on rush hours (and lunch hour on Line 4), and the rest of the day the trains stop at every station like usual.
A simple explanation with spanish and english subtitles of this system is here:

I also left a generic white sign for normal destination signs for the simulator.
With this update, I think both trains are finished
Attention passengers: Metrotren service to Rancagua departing from platform 3.
Mr. Conductor, OK to proceed.
Have a nice trip!
