EU07 Simulator English forum / Oerlikon Fv4a and modern brake valves

« dnia: 20 Grudnia 2023, 16:06:35 »

I've noticed that in the simulator, in modern locomotives (6dgb, E483_202, BR285) the brake valves doesn't do high pressure burst to release brakes, as Oerlikon valve does, them only fill the pipe to 5 Bar, optionally them have a button to slightly overcharge the brake pipe. Here in Spain, as far as I know, never have been a brake valve that does high pressure burst, but I don't know why.

I think the behavior of Oerlikon  Fv4a valve is very adequate, they do a high pressure burst (max. about 7.2 Bar) to ensure the last wagon of a large train gets quickly filled with 5 Bar or more to release its brake in an adequate way, few seconds later the pressure drops automatically to prevent overcharging control tanks, the pressure remain then at a value slightly above 5 Bar (max. 5.4 Bar) to compensate pressure drop when brakes are fully released and auxiliary tanks start to filling. If any control tank gets slightly overcharged there is no problem, the pressure in brake pipe drops slowly to 5 Bar, to reduce control tank pressure without braking the train. Everything is planned with this brake valve, and works fully mechanically!! without electronic control. Oerlikon Fv4a is a very complex valve but I think it does a good job.

Why modern brake valves with advanced electronic control behave in such a simple manner? There are many inconvenients: in a train larger than 300 meters when locomotive brake pipe is filled to 5 Bar, last wagon is filled to 4.7 Bar (at least in the simulator), the brake starts releasing but stops releasing because pipe is not filled to 5 Bar. The brake pipe gets slowly filled to 5 Bar and brake finally gets fully released, but it's a very very very slow process.

Is there anything bad with Oerlikon Fv4a valve? Perhaps it's excessively aggressive?

EU07 Simulator English forum / How can I use SetDamage in events?

« dnia: 10 Listopada 2023, 14:27:10 »

Hi! I'm doing experiments with events. I've modified TD scenery a little to include some events. This is my code:

Kod: [Zaznacz]

//event keyctrl08 multiple 0.1 none przej_1_zamykaj przej_2_zamykaj endevent
//event keyctrl09 multiple 0.1 none przej_1_otwieraj przej_2_otwieraj endevent

//Posar en marxa el tren
node -1 0 ep07_sta memcell 1.0 1.0 1.0 Wait_for_orders 0 0 start endmemcell
event keyctrl08 updatevalues 0.1 ep07_sta Prepare_engine 1 0 endevent

//Trencar el motor
event keyctrl09 updatevalues 0.1 ep07_sta SetDamage 32 1 endevent


The comments are written in catalan, my native language, they mean "start train" and "break engine"

I've added a second trainset, so the original trainset is controlled by the AI. The "Prepare_engine" works without problem, when you press Shift - 8 the AI starts engine automatically, but "SetDamage"  command is not working, you press Shift - 9 and appears this in the log:

Kod: [Zaznacz]

Key pressed: [Shift]+[9]
EVENT ADDED TO QUEUE: keyctrl09
EVENT LAUNCHED: keyctrl09
Type: UpdateValues & Track command - [SetDamage] [32.00] [1.00]
 Memcell: ep07_sta - [SetDamage] [32.00] [1.00]
 Vehicle: [ep07-424]

Apparently the "SetDamage" command has executed correctly, but it does nothing, engine is not broken.

How can I use SetDamage? In my opinion it's a very interesting command because it can introduce random malfunctions.

EU07 Simulator English forum / Change cabin procedure in EU07 (Version 2)

« dnia: 09 Listopada 2022, 12:46:18 »

This topic is related to another I wrote years ago, in 2017:

https://eu07.pl/forum/index.php/topic,29393.0.html

I'm obsessed with that :-) but it's a healthy obsession to get knowledge.

Now my question is about the brakes. You are shunting and you brake with the locomotive brake (FD1 valve). In the simulator, you change cabin and the FD1 valve is in the same position and you can release brakes easily, but in the real life, if locomotive brake is applied in the other cabin you can't release brakes in the new cabin, it's applied all time. Am I rigth?

So, which choices are possible? :

• Release locomotive brake and change cabin. This is a little dangerous in flat terrain and not possible in steep terrain.
• Apply locomotive brake, change cabin, apply locomotive brake in that cabin, return to previous cabin, release locomotive bake, return to the new cabin. With this procedure you walk a lot. Well, it's healthy but it seems a little stupid.
• Apply emergency brake in the train brake valve until pressure drops below 0.3 MPa, then you can return the valve to neutral position and locomotive remains braked. Now you can change cabin safely. This is the procedure I use, but it's a little weird, it wastes air.

So, which is the procedure drivers do in real life?

EU07 Simulator English forum / Why trains must start with two pantographs raised?

« dnia: 04 Października 2022, 19:53:22 »

In the newest version of the simulator (22.08), the "Driving aid" window suggest that whe train is stopped you must raise the two pantographs, and when the train run at about 5 km/h you can lower the front pantograph.

Why is this action done? Is it applicable to inverter asynchronous locomtives, EMU's or light passenger trains?

EU07 Simulator English forum / Change cabin procedure in EU07

« dnia: 27 Lipca 2017, 08:58:06 »

Hi! I'm enjoying this good game, it's very realistic.

What is the procedure to change cabin in a real EU07?

I've seen in Train Driver 2 and in some videos about EU07 that there is a control to enable/disable the cabin. Also, I've seen that the reverser and the enable control are handled by a key that you can extract. It seems there is only one key per locomotive, so you can't enable 2 cabins at same time nor handle the reverser.

So to change the cabin you must put reverser to neutral and extract the key, and disable the cabin and extract the key. But if you disable the cabin the pantograph goes down. Is this normal behavior? Also, there is a control near exit door to the other cabin that is handled with reverser's key, it says "0" and "P". What is the purpose of this control?

Thank you.

EU07 Simulator English forum / New version MaSzyna 17.07 AWESOME!!

« dnia: 25 Lipca 2017, 11:56:28 »

I like so much this new version, very good job, congratulations. This game is better than commercial games.

I liked these details very much:

• Scenarios load much faster.
• Now you can touch the buttons.
• When you leave the cabin, you are on the floor and in front of the door. You are a human, you are not flying, very realistic detail.
• The night is fantastic.

There is only a small problem, at least in my computer, but I have been able to solve it. When you press Num 3 to move the brake lever, it takes a long time to start moving. This is because the keyboard type rate in my Operating System is set to 650 milliseconds. I've set it to 200 milliseconds and it works perfectly.

I use this game from a GNU/Linux system with Wine. Here is the small script I have to start the game:

Kod: [Zaznacz]

#!/bin/bash
xset r rate 200 # set keyboard type rate to 200 miliseconds
setxkbmap us    # set US keyboard, spanish keyboard doesn't works well
LC_ALL=pl_PL.ISO-8859-2 wine RAINSTED.exe # set polish locale and start RAINSTED
# set all things as they are
setxkbmap es
xset r rate

EU07 Foro de Simulador en español / Nueva versión MaSzyna 17.07 ¡¡IMPRESIONANTE!!

« dnia: 25 Lipca 2017, 11:43:41 »

Me ha encantado esta nueva versión, lo habéis hecho muy bien, enhorabuena. Este juego es mejor que los juegos comerciales.

Me han gustado mucho estos detalles:

• Los escenarios se cargan mucho más rápido.
• Ahora puedes tocar los botones.
• Cuando sales de la cabina, estás en el suelo y enfrente de la puerta. El juego simula que has salido por la puerta, muy buen detalle.
• La noche es fantástica.

Tan sólo tiene un pequeño problema, al menos en mi ordenador, pero lo he podido solucionar. Cuando pulsas Num 3 para mover la palanca del freno, tarda mucho en empezar a moverse. Esto es porque en mi sistema operativo no se repiten pulsaciones de teclas hasta que no la sostienes durante 650 milisegundos. Lo he configurado a 200 milisegundos y ya funciona perfectamente.

Uso este juego desde un sistema GNU/Linux con Wine. Este es el pequeño script que tengo para iniciar el juego:

Kod: [Zaznacz]

#!/bin/bash
xset r rate 200 # set keyboard type rate to 200 miliseconds
setxkbmap us    # set US keyboard, spanish keyboard doesn't works well
LC_ALL=pl_PL.ISO-8859-2 wine RAINSTED.exe # set polish locale and start RAINSTED
# set all things as they are
setxkbmap es
xset r rate

EU07 Simulator English forum / Electric brake in EP09 locomotive

« dnia: 06 Stycznia 2017, 23:34:22 »

EP09 have electric brake. How does it work? Is it implemented in the game?

I know how to use electric brake in ET42, but EP09 doesn't work in the same way.

Thank you.

EU07 Foro de Simulador en español / Señal We8a: pasar sin cargar

« dnia: 06 Stycznia 2017, 18:43:20 »

¡Hola! Este va a ser mi segundo mensaje en el foro, hace un momento he escrito este en inglés:

http://eu07.pl/forum/index.php/topic,28697.msg434666.html#msg434666

Pero prefiero escribirlo en Castellano porque así me expresaré mejor. Espero que esta duplicidad no suponga un problema, si no, que los administradores quiten este mensaje si lo estiman oportuno.

Tengo una duda sobre la señal polaca de "pasar sin cargar". En España tenemos las 2 señales que he adjuntado, la primera significa "abrir el disyuntor" mientras que la segunda significa poner el regulador a cero al pasar por el seccionamiento de aire de la catenaria.

¿Que significa la primera señal en Polonia? ¿Abrir el disyuntor o poner el regulador a cero?

Muchas gracias.

EU07 Simulator English forum / Signal We8a: pass without charging

« dnia: 06 Stycznia 2017, 18:30:07 »

Hi! This is my first post in the forum. Congratulations for this great game. It's very realistic, i've enjoyed it many hours.

I have a doubt about the attached signal:

In Spain, we have the two attached signals, the first means open circuit breaker while the second means put power controler to zero when passing by the catenary-section. Have it same meaning in Poland? Put power controller to zero or open circuit breaker?

Thank you.
