I found that locomotives on IC 1279 in Kassel - Würzburg route was a push-pull(as known as sandwich config). The MTD display shows the line voltage and master circiut breaker status max up to 4 locos. So I tried to put 4 locos together, 1(Lead driving)-2-3-4 and follow steps: 1. As soon as all locos connect together, shut down all locos completely, includes the battery and set the multiple control selector to "ZMS". (I choose ZMS because this article: http://www.moebahn.de/t9363f123-Wendezugsteuerung-Wer-kann-mit-wem.html) 2. Turn on battery of loco #4, wait for sys self test complete. Put reverser to N, raise the pantograph, close the master circuit breaker. Put reverser to 0(or X/OFF shows on game overlay). 3. Repeat step 2 on loco #3, #2 and #1. 4. 4 locos BR101 multiple unit complete. When I finish step 2 on loco #1, it does shows all 4 locos on MTD. And then continue finish all other settings. I give full power, but only the front 3 locos have tractions. And when I set full elec brake, all locos output max of 150kN brake effort. Elec brakes are normal, a loco max can supply 150kN braking. But why forward traction only output on 3 locos, what was limited that? And seems "ZDS BR120" mode can only support 2 locos wheather all put them together or separately?
Correct ZDS BR120 is for Push Pull so maximum of 2 locs in lead and behind with coaches in between or Sandwich and it im right ZMS is for double/triple traction so 2/3/4 locos behind each other but more than 2 locos never used in IC/EC traffic maybe in a special situations but not in normal service. And ZWS "Zeitmultiplexe Wendezugsteuerung" is for IC coaches or with the 143/146 with Dosto coaches. And also an older system KWS is for n-wagen with locos with TB0 cwf.green Can you correct me if im wrong Please?
That's correct. 1. ZWS: Only supports a loco + cab car. 2. ZDS: Only supports two locomotives. 3. ZMS: Supports up to 4 locomotives. DB forbids using ZMS on the BR 101 so it's hard to test how it works in practice (as compared to theory), but I will investigate what is going on in your case, though I make no promises when or if it will be "fixed".
Okay after some investigation I know what the bug is, and how to fix it. Firstly, the good news: it is only a visual bug (if you check the MFA tractive effort gauge in that rear locomotive it is powering, it's just not sending the force state to the master locomotive). For the bad news: I found some additional bugs while investigating the issue: 1. Multi traction is broken when two separate locomotives are spawned (either in timetable as part of a "coupling instruction" or in free roam), the locomotives don't detect each other. To be clear: this bug is only experienced if you have two locomotives that spawn split up, and you then couple them together. If you spawn the locomotives coupled together it works correctly. 2. The pantograph auto setup doesn't work as expected on 3 or 4 locomotives multi traction formations (these are forbidden in Germany and especially for the BR101 since ZMS is not allowed, but technically it should still work). Fortunately I've been able to fix all of these issues (including the 4th loco not sending out a tractive effort signal to the master), but a fix will likely not arrive until the BR145 is released (and could take even longer, I don't know and it is out of my hands).
