Hello, I recently bought the DB BR 101 loco and have been experimenting with it. I noticed that you can MU them using the 'ZDS BR120' switch which is located on the panel behind the seat in cab 1 only. In the following configuration ( see screenshots), I noticed that if a locomotive's cab 1 is not facing the coaches, the locomotive will not participate in traction, whereas when cab 1 is facing the coaches, it can. Do you know how I can ensure that both locomotives are involved in traction, regardless of which cab I'm in? Thanks in advance !
Did you make sure that the switch is in "ZDS BR 120" in both locos? From the manual: I've never really messed around with two 101s in a consist in TSW, so that's all I can think of right now.
Yeah to me it looks like the panto of the back locomotive isnt raised. I've been running them in sandwich formations a few times and it works. Although the specific thing with which locomotive has to face the coaches or not, I've honestly never paid attention to that and don't know if it makes a difference. Take Hamburg-Lubeck for example, the ICs running there are automatically in a sandwich formation. And I think some in Bremen-Oldenburg too. And it actually works flawlessly with the ZWS switch. I remember back when a mod for Munich-Augsburg existed that implemented some IC formations with 101's on both ends. There you had to manually set the ZWS switches. But it worked too.
I made some tests with the 101 to look at the tractive load in MU and havent found any issues, i recommend to check your pantograph configuation & MU selector settings (ZDS120 in double traction): All 4 possible directions of the locomotives in sandwich formation produce power to the wheels, tested at köln betriebswerk SKA. Also 3 BR 101 working in MU produce power in ZMS mode, same for 2 locomotives and a "towed" as 3. loco. Everything works as intended.
recently ran into a sandwich config situation in Rosenheim - Salzburg, a service starting in Freilassing and going to Rosenheim... I ran some tests and came with some conclusions... will do some more testing on that service today as well https://forums.dovetailgames.com/th...nts-and-driving-help.51751/page-2#post-828134 be sure to also check other posts in that thread as some ppl share really nice insights into how this all works the implementation might change a bit once we get the expert line BR101 tho
from when I researched it I'll set them up properly with panto on auto and the rear loco first to ZDS BR 120 and then the front set up. As I see in the picture the lowered pantograph on the rear loco seems to be the leading cause of it not getting power.
in a run I did, when testing a setup where I only set up the lead loco cab (ZDS off), it seems that even with ZDS off, if the rear loco has panto raised, it seems that the lead loco gets some more juice from there... or am I mistaken?
I'm not sure. but to be honest I thought the game spawned in sandwich services with already correct ZSD BR 120 set up. it's been a while since I drove one so not sure.
in Hamburg Lubeck, it does come already with ZDS turned on, elsewhere I usually encounter ones where you have to turn it on... I hope this stuff, including some instructions on it, will be included in expert line loco manual... would be nice to have an official thing instead of having to spend a lot of time researching it everyone by themselves
https://vdoc.pub/download/richtlinie-4930101-triebfahrzeuge-bedienen-baureihe-101-3sv9o8v3ohp0 Here the real docu for DB drivers. The "Vielfachsteuerungen" (MU Control System) is not something which is unique to the 101. Same goes for the ZS 1000V calbe or the UIC control jumper cable. I recommend to study the technic of locomotives in general, and you might find similarities for a better understanding. In my opinion its probably better to start dealing with brake systems, rahter than the MU related things. If you manage to understand how an air brake system is working, you rule a beast, because this knowledge covers a wide area in european railway. (In case you play the BR diesels, you probably have noticed the 72.5 psi are the 5 bar, just a different unit. The HBL Hauptluftbehälter Leitung is the Yellow Mainreservoir Pipe in the UK, And the brake pipe is even identical in the colour red. )
Lol, my past posts in this thread remind me the time without freeroam, which took 3-4 hours to get those consists together with ductaping and shunting.
oh wow thx for the pdf, with some google translator and my own brain I might figure stuff out... so far I skimmed the important part, and pls let me know if I understood it correctly: 1. in the lead loco, put the reverser into neutral 2. open MCB and drop the pantograph down 3. turn on ZDS BR120 switches in both locos (I believe only one cab in each loco has this switch) 4. return to the lead cab and raise the pantograph, then close the MCB 5. set up the rest this is what I understood from the pdf now, comparing it to the setups I tried, two options seem like the ones that should definitely work - first do the ZDS BR120 switches in both locos, then return to the lead loco and set up everything OR set up everything in the lead loco, then turn on both ZDS BR120 switches, then open MCB/drop panto and raise panto/close MCB and finally, in my understanding/testing, the way it is probably implemented, as long as both ZDS BR120 switches are on in the moment you apply throttle and depart, the formation should work as intended this seems very similar to how AFB engagement has been explained in various places - official way, when going out of LZB, in motion, was to set throttle to 0, then the AFB to max (if I remember correctly) and turn AFB off and back on or sth like that... and then, a genius of a guy in this forum, said sth like, why the hell do you it in such a complicated way... just drop throttle to zero, and when LZB ends, drop AFB lever to zero, which disengages and resets it, and then just move the AFB to target speed and reapply power when I have more time and most of all more energy (I should really sleep more or better), I might start compiling such user guides into a document, which I will then share with others... I mean, there are things like this one that are not in manuals, at least not the official ones for the game and it takes work to find them, so, it might be useful for ppl to have such info handy thanks a lot for your input and... will let you and others know when I get to creating that document
tried additional method: 1. in the lead loco cab, I inserted reverser, put into neutral, used that to open MCB and lower panto, then put reverser into off 2. in the rear loco cab, I inserted reverser, put into neutral, used that to open MCB and lower panto, then put reverser into off 3. then did the ZDS BR120 in both locos 4. then in the lead loco cab, I inserted reverser, put it into neutral, raised panto, closed MCB and then reverser into forward 5. finish setting up the lead loco cab no real benefit, but yet another way it worked
If you want to do sandbox testing and compair it with real), maybe better wait for the 101 expert line. For a tsw loco, the 101 is very detailed (despite its missing brakemod selecting p/g/r).
