Tehachapii Pass Train Braking

[chrisreb]

I am playing the second part of the Hot Box Career scenario. I have Dynamic Braking at full and brakes at full but am still gaining speed. No special instructions in the manual so was wondering if some kind soul might give some pointers where I am going wrong. Other stock clearly sounds when Dynamic Braking is in effect but on this loco it is silent.

I had that problem but solved it through trial and error. Make sure the brakes are in easy mode I'm not sure of the keys may be shift 1, 2 or 3. Take the train brake no further than 80 to 88% and no further or as you have found they release. As they are slow to come on put them on about a mile before the decent. once up to pressure and working you can release them a bit if you need to but don't fully release them. I would imagine that it is not the correct way to use them but that is how it is.

OK will try that thanks

The AC4400 works as expected

Hi all

did some examinations, seems DTG messed up the bin file of the ES44 engines. In general it is the engine used in the Linovia Subdivision AddOn, but they changed the description of the notches for the TrainBrakeControl. I copied ovver the notch setup from the Linovia ES44, and all seems to be fine now.

For those who want to test it, and are a bit skilled using TS-Tools, here is what to copy in the bin files:

Open the bin of the BNSF or UP ES44 engine, and search for "TrainBrakeControl". Scroll down until you see a section starting with <Notch> and ending with <\Notch>. Select this section including the Notch tags, and copy this over:

<Notch>
<cControlContainerBlueprint-cInteriorIrregularNotchedLever-cNotchData d:id="70164">
<Identifier d:type="cDeltaString">Release</Identifier>
<Value d:type="sFloat32" d:alt_encoding="0000000000000000" d:precision="string">0</Value>

</Notch>

Save the file, and you should be good to go :-) Please make a backup before, and be careful what you do - you do so at your own risk. I fixed only one engine now, after the fix for the other also works, I may put the files in a share, so you all should be able to get ready prepared files.

Thanks and regards

Thorsten

Interesting find thanks.

Hi all

here you have some adjusted engine files, please let me know if these work also for you. Did some runs, and found the brakes to be working as expected:

For the BNSF ES44, the files go to "RailWorks\Assets\DTG\ES44AC_BNSF\RailVehicles\Diesel\ES44DC\BNSF\Engine" below your Steam installation path (you likely will have to create the folder structure, since content is packed into an ap file):
https://1drv.ms/u/s!AhmLWyeq-a6ojbtdV5k ... g?e=D0YQ4G

For the ES44 UP:
Files go to RailWorks\Assets\DTG\Tehachapi\RailVehicles\Diesel
https://1drv.ms/u/s!AhmLWyeq-a6ojbte69W ... w?e=aeCNLi

[chrisreb]

Will give them a go thanks although my installation does not have the BNSF folder - maybe because I am not in USA

[thor1969]

Oh ok - I am also not US resident, so it should look the same for us. The BNSF engine is installed separate as it seems, rest of engines can be found in DTG\Tehachapi.

Great find mate!

You can also activate the ditchlight by changing "Fwd_Headlight_03" to "DitchLight_R" and "Fwd_Headlight_04" to "DitchLight_L" in the engine's .bin because those are referenced by the engine script. The beam will be toggleable but the lamps appear to be off still.
This is one of the most f'''ed up locos DTG has ever released, together with Clinchfield's SD-40.
