    I was under the impression that with distributed power, the driver (engineer) remotely controlled all the units in the train, whether they be front, mid, or rear. This presumption got me into trouble when I played the Fully Fuelled scenario. Visibly DTG simulate manned banking units, hence the banking radios. Wish I’d known that then because I dragged the whole kit and caboodle up the mountain at about 8 mph lol.

    They did, because no locomotive presently in game is DPU equipped in real life.

    This is an interesting compromise, but it could use some clear information that all DPU-like configurations are multi-MU or virtual helpers (as long as the radio works).
    Interesting. AC4400 is not DPU capable? << This is not a rhetorical question! :)

    DPU capability was an option for both AC44 and Dash 9. Railroads with hilly routes like BNSF or UP mostly opted to have DPU equipment on their units, but CSX is one of the RRs that did not. CSX's AC44s are currently receiving that equipment as part of their rebuild into CM44AHs. That's why most distributed units you will see on CSX these days are their AC GEVOs. Even their DC GEVOs are not DPU capable.

    Actually both the AC4400 and the C40-8W are. It's hardly new tech. And some other railroads (notably Norfolk Southern) have rigged their SD40-2s for remote DP operation as well.

    That's interesting. CSX has its own strange habits (eg moving away from humping). Perhaps this has evolved recently over the years. Thanks for the info!

    ...some good info here, thanks for posting it. How did you become aware of all of this- which locos include DPU functionality IRL, which locos are being upgraded, etc? It’s funny... I watch plenty of (US) train videos on the ‘tube- have never seen a GP38-2 in a DPU spot in a train that I can remember... now I know why.

    ...link to a video of a DPU unit train I put together in Oakville Sub (Hamilton Explorer scenario) long ago, complete with buffer cars appropriately placed:

    CSX' network doesn't lack for hills......

    It is not impossible that it was a union contract thing. DPU puts helper crews out of work.

    This is not a DPU in TSW. This is some multi-MU / virtual helper via 'radio'. Loco doesn't matter in this mode.
    Fully non-prototypical! :)

    ...not sure about that. In fact the GE ‘Locotrol’ DPU control devices tie into the cab radios in real life. The cab radio (or possible a secondary radio) have to be used to handle the transmission of the radio signals used to control the remote (unmanned) lead loco in the DPU consist in back.

    I checked all of this out months ago now... I actually found pics showing the Locotrol device mounted in a rack in the nose of the loco, and found other pics that showed matching connectors used to connect the Locotrol to a cab radio. So they do tie together, and work together to control unmanned DPU units via radio. Now if the DPU units have no Locotrol device in them to allow radio control, then those would have to be manned of course.

    (EDIT: added info on the use of a dedicated secondary radio with the GE Locotrol DPU devices, freeing up the primary radio in the cab from handling DPU comms)

    But here it is a 'radio-cheat'. Other settings are not DPU-like (lead/trail).

    PS Or they are just not correct. In practice, it works like DPU. Full agreement. I do not judge realism!

    Even in a full radio-remote DP setup, each MU component is still set up lead-trail-trail, just as if there were a live crew there.

    Exactly. In my opinion - a nice game-style compromise.

    Various forums + watching videos. This is where I just confirmed what I was pretty sure about. Note that it's from 2017, since then CSX received 10 new DPU-equipped ST70AHs (SD70ACe-T4) and the forementioned CM44 rebuilds.
    There are quite a few radios on-board a modern locomotive and they even use (they have to use) more than one antenna. I don't know much about this technology, but this document includes nice photographs of all that stuff.

    I meant, in real life it's done that way. No need to overburden the radio bandwidth with trailing locos when you can just plug them together the old-fashioned way.

    I've been playing around with multiple unit control in TSW2. Is it possible to have a trailing unit have the engine idling but NOT controlled by the lead unit? Googling lead me to believe just turning the control stand switches on for engine run, fuel pump, and generator field should make it "ignore" the lead unit, but it seems to still respond, at least judging by engine audio and the amps indicated.

    edit: Also, do the headlight control switches work as they should on Sandpatch or Clinchfield? I have each unit in the consist set to be controlled by units at either end but the rear headlight switch isn't doing anything. It does work on the Peninsula Corridor SD40s though.

    The headlights work properly in Sand Patch. The SD40s in Clinchfield do not work correctly.

    In Sand Patch, intermediate units should be set to "Single or intermediate". If you set one to a "control" setting, it "breaks the chain" and prevents commands being sent to the rear loco in the MU. (Note that these controls ONLY work for locos coupled together; DP MUs have to be set up independently)

    no effect on scoring since freight services do not have time tables in TSW2

    Hmmmmm . . . then why does a score always appear after I've completed a timetable freight service?

    Freight runs are scored on observing speed limits and accurate stops, but not (unlike passenger runs) keeping to a timetable.

    When driving the Ace on Sherman, with 3 or 4 units at the head end and one rear helper, I did nothing more than set up the lead loco as Cut in Lead and turn on banking com and all the locos fired up just fine.

    That's not in fact true; AC4400s and SD70s (and ES4400s) are. However, the game doesn't model DPU

    Perhaps in some cases, but certainly not in the switching sessions available for Sand Patch, in which speed is of the essence since in many cases sessions overlap, making completing one session impossible because another session with a later start time couples to the freight cars to which you are assigned to couple, thus preventing you from completing your session. This happens with many of the "Y" series of sessions.
