    Good evening to all,

    I recently started using the North London Line map again and I realised something: it is impossible to switch from 3rd rail to catenary mode and vice versa. For the 3rd rail -> Panto direction, the shoes go up, you can hear the pantograph sizzle but it doesn't go up. For the direction Panto -> 3rd rail, the panto goes down but not the shoes.

    Even when I press Y, the button that normally does the manoeuvre automatically, the grey box at the top right of the screen doesn't appear as it should and when I press Y again, a box appears with "the change of tension mode is already in progress". Even after waiting 5 minutes, nothing happens. With the "manual" method (i.e. pressing the buttons in the cabin) nothing happens either.

    I have searched on forums for the solution for a very long time, I have tried everything but absolutely nothing changes.

    For the record, I have the Class 378 add-on, the North London Line add-on AND the North London & Goblin line add-on as well as the AP sound patch, now no longer available for sale.

    I tried to do the manoeuvre without and with the AP sound pack, and it didn't make any difference either.

    Does anyone have the same problem? Does anyone know if there is a solution? And why doesn't DTG make a patch? It's been 8 years since the add on came out and still no patch!

    I thank you for reading and for any help you can give me

    Have a nice evening everyone

    Works ok for me. Both Overhead to Third Rail and v.v. -
    I have no idea what the "Y method" is? Nothing in the Instructions.

    I pushed Shoes Up then Pan Up and it worked
    Then Pan Down - Shoes Down and that worked
    The messages appear as you do each sequence

    So DTG should make a patch because a few people have a problem with an Add-On?
    A lot more people would be complaining if the DLC was Faulty .It could be something wrong with your setup

    Are you running in Expert Mode or Simple Mode?
    The instructions for the 378 are fairly rubbish but I know some AP Add-ons don't work in Simple Mode.

    In fact, I am not at all the only one to have this problem. I've looked on many forums and many have it like me. This bug is a matter of luck: some have it, some don't, for no particular reason. I unfortunately have it. I'm running in Expert Mode.
    I tried what you told me and it doesn't work either. I think it's not hard to come up with a patch that works for everyone and it's a shame I can't use it fully, I love this train.

    I had no issues with the route / stock a few years ago, already 64 bit.
    Do you have either of the London-Faversham versions? It has a similar procedure.
    I recall in both cases you have to switch off the current system first, then switch on the new one (or the same).
    What can be confusing the pantograph is lowered, while the shoes are lifted.
    Might be a LUA issue or something OS related, or interaction with some enhancement or other rolling stock (like physics on my PC are / were way more pronounced than for others, no idea why).

    I can run a scenario out of curiosity if a few more people report having issues. Been a while.

    Don't think there's a Lua issue - TS uses its own DLLs independently of the OS.

    Give me an example spot (route, location) so we can test this under the same conditions.

    Note that I said it did work for me, just in case :) So I'm just shortcutting the answer for the OP.

    There are two locations on North London Line (vanilla), featured in scenarios.

    At Acton Central you change while boarding, both systems are available at the station. Scenarios 2 and 5 cover it, including tutorial popups. In a QD, you can come from Richmond.

    After Canonbury there is a switchover that you do on the fly. Scenario 6 runs that section. Plays the same as GCT connection to New Haven. I don't think QD covers it, it is specifically for joining the line.

    You could also execute such a power change at Ebbsfleet on London-Faversham in a quick drive right away.

    I didn't know about a quick power change option.
    Consult Page 9 of the manual. That said, I don't think it's covered in the manual at all, but in the scenarios. (Same as the 395 on London-Faversham.)

    By the way, I can imagine a slim chance that there are multiple 378 versions around, South London is the same at first glance, but there could be such differences.

    We have to use the exact same versions of course - I was thinking of DTG\Class378Pack01 which has scenarios for South London Network (It's the one with the missing sounds)

    North London & Goblin brings its own, so which one has the issue?

    simeon.hellier Give a scenario we can all test to make sure we're using the same 378.

    Well, that could explain it. I didn't think much of it, but the manual says...

    "Today, there are 57 Class 378s in service, there are 20 /1s which are 750V DC third Rail only, and there are 37 /2s which are dual voltage, sport ing the third rail shoe and a pantograph for the 25kV AC catenary."

    Of course when driving the /1 it will be hard to change modes. :) Even if some buttons are there.

    In any event, the procedure is super simple if I recall correctly. Power off, turn off current system, turn on new system, hear some vents coming on, proceed. (Since you can changeover on the go, of course you can have the reverser active and you can have brakes off and keep rolling.)

    upload_2023-3-12_8-56-26.png
    upload_2023-3-12_8-56-40.png

    Blue first, then yellow. I guess you can even push both blues when confused, shouldn't be a problem.
    (I have a hunch in real life you have to press the button underneath the red cover, too, for added safety-in-complexity.)

    My first guess is that the OP is pushing two of the same, because one says Down the other Up.
    Since "down" is often a term for off (systems down, power down).

    ps.: I think this is a great example why Pro range (and TSW) can get problematic. I know this isn't, but the principle of pressing stuff that you don't normally do.

    Checking again - all routes are using the DGT\Class378Pack01.

    This pack features SLN scenarios, and it's bundled with the NLG. So only one.

    Successful changeover at Acton. (Though the scenario incorrectly tells you to first raise the panto then the shoes - it's the other way round).

    I can't see any bug with this.

    I did scenario 5 and worked fine for me, so I guess the issue is local and not a software issue.

    The scenario pauses, tells you what to do and even zooms in to the panel, so unless you press the wrong buttons, it seems ok.

    it still doesn't work
    I also think it's a personal problem although I've tried on 4 different computers and I still have this problem
    I'm not sure if it's a bug in the 378 script, in which case I have no idea how to fix the problem.

    What did DTG say when you reported the problem?

    They told me that for them the 378 worked very well and that they did not have this problem

    So do Quick Drive and pick the Correct 378 - a Dual Voltage version and see if the switchover works when you follow the sequence.
    *** You Don't have to be on the Goblin Line or any route with Dual Voltage - as long as it has either AC or DC ***

    Remember you have to stop using one type of voltage before using the other.
    AC to DC Pantograph Down then Shoes Down
    DC to AC Shoes Up then Pantograph Up

    It still doesn't work! I have tried exactly that and I always have the pantograph down and the shoes up (or the shoes up and the pantograph down)
    I'm losing hope

    Just tried this, and pressing Y worked as it should - of course used a 378/2 (which has both pantograph and 3rd rail) - started a quick drive at Acton Central (doesn't really matter where you put it to be honest. Pressed Y - Pantograph Lowered, and then the shoes lowered after a couple of seconds with messages. (I think perhaps you may have some other mods installed? - or are using the WCML South version? )

    Yes I have the AP sound pack, but I've tried it without. I tried the NLL version and the WCMLS version

    I can only think you are doing something out of sequence as it works for everyone else.
    You could try this when the game is Not Running

    Go to \steamapps\common\railworks\Assets\DTG
    Then CUT the Class378Pack01 out of the folder and place it somewhere outside the game.
    Go to your Steam Client then Library > Train Simulator > Manage My DLC
    Search for Class 378 and untick it - wait a couple of seconds and re-tick it
    Steam will install a fresh copy of the Class 378.
    Before applying the AP pack try running the default train on ANY electrified route. - It does not need both AC & DC just one -
    You should be able to run Third Rail and Pantograph modes even if the route does not have both.

    I've just tried it and it still doesn't work. I don't understand anything any more. I can lower and raise the shoes as I like but when I press the pan up button nothing happens. The Y button doesn't even work any more.

    My comment on the train running anywhere was wrong.
    I can run in AC mode with OH Wires and DC Mode with Third Rail - But I cannot get the unit to run in the wrong mode.
    I have done it with other trains such as running a Third Rail EMU on the GEML

    Can you try a Quick Drive 378/2 (Overhead) on a route with OHLE - not the Goblin/NNL routes - does it work?
