Powering America Part 2

Hi everyone! Pretty new here. Bought TSW2 a few weeks ago and have been working on the Sand Patch Grade journey. I’ve made plenty of mistakes, but then searching here and elsewhere online I’ve usually found what I’m doing wrong and been able to complete scenarios. Not on this one though…

So I get up and over the mountain, and on my descent I keep having derailments. Based on the earlier scenarios tutuapp at first I tried controlling speed with dynamic then adding auto brakes as needed, but I derailed pretty quickly 3 separate times.

I decided maybe this engine was too strong for that strategy so went for auto first then adding dynamic as needed. Got much further this time, then without warning I get the derailed pop up again.

Any ideas on what I’m doing wrong? I really thought I had it this time so when without warning I failed again I got pretty frustrated. Hoping you all can help! Thanks!!!

 

I don't think you are doing anything wrong. The game seems to be broken at the moment when it comes to braking physics. Try using the independent brake to control your descent.

 

Just lately- since a recent patch - players have been reporting unexplained derailments on Sand Patch.

 

Ive not tested it since todays update but from reading the patch notes they have made a change, hopefully this has addressed it, or atleast reduced it.

Had you installed the update prior to the derailments today?

 

I'll have to check this out. I've been playing SPG for years and never experienced a derailment. The only serious bugs I've had on the route involved dynamic brakes on some of the locos.
It can be a challenging route, but I've never been unable to complete a scenario or service.

 

Can confirm, I'm new to the game and have been playing for just a week or so, before and after the latest patch. I have not had any problems before with any Scenarios on Sand Patch Grade, but when I was starting out Powering America Part 2, all is well until you let the second train past the repair section near the summit and start heading down towards Cumberland Yard. As you're controlling downhill speed, the train will spontaneously derail, I've tried it with and without the rear DPU engine engaged. You can get it to derail using Dynamic Brake then adding in some Automatic Brake as your speed and the declination increases, sometimes it will just happen when you use only the Dynamic Brake. Not sure if it's a bug with the route or with the AC4400W, no such issues with the 38 or 40.

 

Speaking as a Sand Patch veteran, I can confirm this one now. The first danger spot came at the signal that would hold you for the passing train if necessary. Right when I hit this signal, my train gave quite a jerk for no apparent reason. I was only going about 12 mph due to adjusting dynamics for the decline, but I can easily see that derailing me if I'd been going much faster.


But further on, right when the distance to the stopping point increased from 12 to 13 miles due to the track's northward direction at the time, I started getting wheel slippage out of the blue and my speed jumped from about 25 to 31. I maxed the dynamics, got some speed relief and no more slipping, then added the lowest notch of air brake and got the speed back down to 26. I brought the air brakes off...and then the train spontaneously derailed anyway despite behaving fine during the whole slowdown.

 

I have had derailing issues with the C40-8W heading downhill recently as well. Not sure the exact location, but if I run into it again I'll try to mark it.

 

Yeah, just to add to the list - there is something definitely buggy or a glitch. I'm experiencing a repeated derailment issue at basically at the same spot mentioned in the previous posts above for this scenario.

 

It's definitely a bug with dynamic brakes on the AC4400W Loco. Can we convince DTG to livestream it one of these days so they can see? SD40 has no problems and using brakes on the AC4400W, same, no derailment.

 

Is this still an issue? Playing this on TSW 2020, I've had no problems after setting up the locos properly.

Start from the back loco (which must be configured as DPU Lead)
DPU&Radio fuses ON, EngRun, GenField & FuelPump ON, Brakes CUT OUT / LEAD, Auto brake Handle Off position & Indy Released. The brake handles will mimic the position set in the lead engine later.

2nd (MU trailing loco)
DPU&Radio fuses OFF, EngRun, GenField & FuelPump OFF, Brakes CUT OUT / TRAIL, Auto brake Handle Off position & Indy Released

Lead engine:
DPU&Radio fuses ON, EngRun, GenField & FuelPump ON, Brakes CUT IN / LEAD.

No derailments and no jerky motion.

Apologies if this is not relevant for TSW3.
