Not everybody knows this, but the BR 103 did in fact have an AFB. These were taken out of the locos eventually because they'd often end up switching constantly between two traction notches, but they were part of the locos for a while. This is also visible with the numbers around the tap changer, ranging from 30 to 200 km/h. The AFB would be activated using the control selector (labeled "Auxiliary Control" in the game), by switching it to the "Automatic" position. Doing this in the game simply locks in the current power level, though. I tried a few different ways to activate it: Switching it on while stationary with the tap changer at 0, switching it on while above 30 km/h with the tap changer at 0, and switching it on while above 30 km/h with the tap changer at 39. Since nothing worked, I'm either missing something, or the AFB simply isn't implemented. The point of this post is to say that I, personally, would love to see the AFB implemented in the game, and to ask for opinions on this and whether this might actually happen in a future update or not.
I see. I understand the reasoning behind that, but I still would have loved to see it usable. It would have been the case in real life, too, at least on some locos, that, while drivers weren't supposed to use the AFB, the loco would still have it, and it could theoretically be used (and some people even say that some drivers still sometimes used it, but those are just rumours of course). But again, I do see the reasoning and I guess it isn't a big issue, or an issue at all, really. It still would have been fun, though.
Someone said in another thread that the AFB was removed because it was a very early version of it that was changing power from 0 to 100% too frequently and it caused engine problems.
I have just noticed it today as I was preparing my loco for the run... so auxiliary control in BR 103 is in fact sth like AFB in disguise? then what do the other options mean? You mentioned Automatic means kinda AFB, then Trail is default (no idea what that means) and others I have no idea what those are... anyway, does this switch in any option do anything in the game or should I just leave it at default Trail?
LZB/AFB "autopilot" was pioneered on the E 03 prototypes in 1965, which ran on a specially prepared section of track between Munich nnd Augsburg during the 1965 Technology Expo in Munich. But, yes, this early implementation of AFB was way too hard on the transformer taps so unltimately it was disabled.
