Hi all, after the Update from the 5th November which was supposed to fix the 146.2 nothing has changed for me. The 146.2 still doesn't really reach its top speed (oddly enough when I was driving it from the control car it reached its top speed). Whats kinda more annoying is the sound though. The high pitched whining sound should cut out somewhere at lower speeds, in TSW2 its just stays there all the time and the loop is very audible. Makes the 146.2 at least for me personally undriveable, as I really can't stand the sound over longer times^^ Oddly enough the 146.2 worked absolutely flawless in TSW2020.
That high pitch sound is the real one produced by this type of electric engines used by those locomotives and the ICE trains, and is like in game in real life. The loop has two phases and you will notice the engine transition at low speeds. Cheers
That's the point, the 146.2 has, and because of how it works it cuts power early and doesn't let you reach 160 km/h on straigh and level track, hovewer, you, being smarter than the AFB can manage the power better to hold a higher speed (so for example when you use the same loco without AFB via the cab car)
In the 146 I am using the AFB. Shouldn't hinder me on reaching 160kph though. And I know that the sound itself is realistic, BUT when driving along like 160kph the loco is not producing a whining sound that loud. Just watch some videos of it in TSW2020, it worked fine there.
It does, try not using it and you'll see the difference, which you already saw when driving the Cab Car
I do not doubt that. However, when I select 160kph in the AFB the loco should also drive 160kph. Thats how it is in reality and also how it is with other locos ingame.
With the AFB set to (max) 160km/h the 146 reach the 156km/h. In the same point of the route, without AFB, the 146 (same composition) reach the 168km/h.
Don't know about real life (how it "should be") but I know that in game it makes a big difference, particularly if you are going uphill. If you have any experience or knowledge on how the real life AFB works and the one in-game is wrong file a ticket or post it on "Technical Reports"
[QUOTE = "sequencer2k16, post: 203515, member: 19347"] Le macchine di controllo non hanno AFB. [/CITAZIONE] È lo stesso nella vita reale?
He asked: Is it the same in real life? Credo di si, in quanto le pilote devono interfacciarsi con vari tipi di loco usando il telecomando, ha senso che abbiamo controlli un po più semplificati per assicurarsi di non creare inutili complicazioni. Magari è impossibile controllare l' AFB via telecomando direttamente... ------ I think so, the cab cars have to be able to work with a wide variety of locos, so it makes sense that more "advanced" controls such as the AFB is missing, maybe it's just impossible to control AFB remotely...
Yes, it is like real life, not every train has AFB. AFB (Automatische Fahr- und Bremssteuerung) is only a kind of cruise control, and not mandatory, except for autonomous trains. See it as a support system, not a safety system.
Y'all are likely right, but I still think its kinda odd, that it doesn't ever reach 160kph with the AFB enabled. Other locos do it as well, why shouldn't the 146 be able to. Also, in TSW2020 it worked as it should. Besides that, the sound sadly is still faulty. Even if the loco was fixed with the update where it said 160kph top speed is revised and that maybe enables it to go more than 160kph without AFB, it was also stated that the sound loop would be fixed, for me the loop is still very much audible with the complete sound of the loco being... off..
The BR143 has a max speed of 120. The 185.2/5 is hauling freight so max speed 120 anyway. The 182 is an IC loco built for operating at 200km/h so it's much more powerful and the little power the AFB uses it's enough to reach 160 406/403 (ICE3) and Talent2 are too different from the loco hauled stock. But seems like Tempomat on the Talent has a slightly different logic than AFB 422 and 425 have no AFB, I do not own HMA so I don't know how the 423 under LZB performs. Anyway, the sounds are still a bit bugged and worse than in TSW2020, but a lot better than before, especially at high speed.
I don´t know how it´s done in game but real AFB is usually adjusted per train type, meaning that it has a mini-braking curve model included to be able to reduce speeds and stop train in a smooth way (mainly using electric brake). In the same way it will accelerate smoothly to avoid unnecesary power consumption. Remember it´s just a cruise control, not a driverless system. So it´s possible you are not able to reach top speeds in slopes with AFB but only with manual driving, as AFB will most likely set 100% traction power target in very few situations. This also prevents wheel sleep upon departure, as AFB does not have any information at all about your current train lenght/mass nor track gradients, as other systems like ERTMS have, so it´s unable to anticipate that an overspeed will come ahead due to downhill drive. That´s why it stays on the safe side (usually a little bit below the target speed) to be able to detect the acceleration when entering a downhill drive and have time enough to apply brakes if traction cutoff was not enough. But when AFB is used together with LZB or ERTMS then we have a different scenario, as those systems know the track gradients and the speed restrictions ahead and they calculate the ideal braking curves to reach the target speeds and send those calculated target speeds to the AFB via the vehicle bus for instance, like in the ICE3 trains case. Then AFB sets the required target speed continuously and the adhession to the optimal speed limits is much better. You can see how AFB sets the power targets by looking at the KN indicated value in the main display. Driver can always push engine to the limits. AFB is not intended to do so. It will just try to stay close to the target speed. Cheers
That's intriguing since in TSW it works by just limiting traction when you get close to Vsoll, it doesn't affect performance in any other way if you are accelerating, since you control the throttle manually, I had no idea it always came into action even in the first acceleration phase (unless you accelerate by having the throttle to 100% and slowly moving the AFB lever up until you set it to the correct speed but I doubt it). Just out of curiosity, are you a train driver or just a big railfail with a bit too much spare time? I'd love to see improvements to AFB and all """driver aid""" systems since it feels they are a touch too basic to be believable, but I just assumed it was just me being too much used to aircrafts...
The throttle lever in AFB simply limits the max power you are allowing system to use. Normally you operate AFB leaving power at 100% setting and just setting a target speed manually when you require new speeds, but you can also put power down to lower values. AFB will not overpass that power setting but will most likely never reach the target speed if power is too low or target speed is too high. Both things work well in TSW. They even implemented the two different methods to activate AFB (while moving or when stopped). In general I would say DTG reproduces quite well the features of most systems they implement in the trains (the ones I´m more familiar with at least). You notice it cause sometimes they put small details into them, even if not really relevant for gameplay, but cause the real ones also have them, like the brightness and contrast controls on the screens or the day/night mode (the color of the screens). Other good detail are the auxiliary shunting controls placed next to the cab windows on german trains. They are functional and they work as expected. And the ICE3 cab window opaque control, which is something I was not expecting to see in the sim. They try to reproduce as much as is possible and be as close to the real thing as it´s possible for them too. LZB for instance has much more things as is a complex system, but the main features we need in the sim are included. I´m a fan but I also work with signalling systems. I spent 15 years testing high speed trains in my country when I was younger, so I still remember many of those things. I think sharing them can help if somebody has doubts. Cheers
Thanks for the very in depth answer I really appreciate it good to know TSW replicate those systems correctly
