Cajon pass "up and down" houston to los angeles trip issue

[Woomination]

The downhill trip from Houston to Los angeles is prolly the worst trip yet. I have gotten bronze on that trip because the train refuses to brake properly even though I had the dynamic brake setup correctly and the automatic brake on minimal with bail out active and yet the train kept on speeding up. Even with all the brakes maximum force working wasn't slowing down the train even slightly. Only handle off or emergency brakes were only able to slow the train down even slightly. It's ridiculous how the train has butter for brakes

Dynamic brakes are most effective between 10 and 30mph, do not leave this range.
Aim for 20-25mph and the descent should not be a problem.

Are you trying to do "up down left right ABBA" Scenario or a Houston to Los Angeles timetable route there are many, but I am not seeing up and down.

The trick is to start slowing down sooner than think, there are several runs like that, using the dynamic break and the auto break as needed and only using the direct break as a last measure, it is tricky but it can be done.
If it shows that can do 40Mph, get the train to 25/30Mph and get ready to engage the dynamic break just before you start to see the downhill section.

I started engaging the dynamic break at 17 mph already and it still kept rolling quicker and quicker to the point the dynamic brake had no power over the train anymore

The scenario is the grain train in the sector "Ups and downs" of the rail journey list

okay, I will take a look and see what is happening, I will let you know.

I'd say you're not engaging the auto brake soon enough - the dynamics can come on quite quickly (after their initial ~10 second setup) but the auto brake takes a long time for braking power to be applied along the whole train. If you're already maxing out the dynamic before you add in some more auto (and bail off) then it's already too late and the train will often run-away before the auto takes effect (compounded by the dynamics losing significant amounts of power above 30mph)

I tried this with TSW3 and 4...

Okay, I spent a good amount of time trying to get this route completed without overspeeding, on my last attempt I literally got the train up to 10Mph and put the throttle into neutral, and tried to use the weight of it to keep moving, by the time I was at the point of the downgrade that starts at around 0.6 down-graded, it was moving at about 3.5Mph, and had it at notch B8 by the time I reached 7Mph and from there it was just the weight of the train pushing me down the grade.

I never used the Auto brake or the independent brake, and the only way I could keep from becoming a runway was deliberately putting it into emergency braking and by doing that activating PCS fault, which would bring it to a stop and even that took a fair amount of time.
I did the PCS reset and let just the weight move the train, I did this three times before I just gave up, I have done routes similar to this and never encountered this before, something is off on this route, it's a clear night no wheel slip, and all 7 locomotives were applying dynamic breaks, I just could not keep it under 30Mph with the 94 car consist.

As "Hiro Protagonist" said, the auto brake alone is not enough taking too long to engage all the brakes because of the length, and when the dynamic brakes at active they are null and void when you use the auto or independent brakes even at minimum application. By deliberately putting it into emergency braking it is dumping the brake pipe of all air activating the brakes on every car and loco. And this is what is odd, if that works then why is it not working when the auto brake is applied and early enough as I did try when I was creeping at 10Mph or less?

And I had everything set like:
Lead Loco as normal with banking comms on,
DP was turned on -every loco-
Loco 2-4 trail cut out and yes they were responding via banking comms.
Loco 5 Lead Cut in and it was responding to banking comings, throttle, and dynamic brakes.
Loco 6-7 Trail cutout.
Using the fly cam I looked at loco's all were showing dynamic braking above 70 and into 100%

With the updates that were pushed out, DTG did push some kind of update to TSW3 or at least they were going to? Who knows what was done to the core game? I do have one other idea that I will try but not sure it will be any different. One thing is for sure something is just not right with this route, from stair lights to walkway lights on at one point then off while the switch was not touched. Maybe the PC needs a reboot to clear things up and let the game(s) get a fresh startup so all assets load in.

Oh yeah also in TSW3 the route shows 21:30 to complete.
And in TSW4 it shows 44:00 to complete.

Not giving up yet on this, I will be getting back to you on this thread as soon as I find out anything new.

The only way I could prevent runaways, was to activate several individual car (aka 'wagons') brakes

The last time I tried this route, I isolated loco #4 but I'm unsure if that helped, but again I put it into emergency braking just as it reached 25Mph it did stop, and I didn't have to go through the PCS reset, light didn't even come on and this what leads me to believe the scenario/route is bugged.
