Hello all, I wanted to dive into this and see if anyone has experienced anything different. It is my impression that DP does not function properly in TSW2 Sand Patch. I am doing the Q353 Manifest Cumberland to Willard. This starts with two AC4400s in front and two in the rear. I do know how to setup what "should" be DP and here are my steps then I will explain why I think it does not actually work in game. Lead. 1. Set Ind Brake to full. 2. Set Auto Brake to release. 3. Open up Air Settings and Select Cut-in and Lead. Save. 4. On the three "control" switches, turn all on. 5. On circuit breaker panel, turn on all breakers on the top two rows. That includes DP. Lead Trail. 1. Ind brake, Auto Brake, and Air settings are all set correctly. 2. On the three "control" switches, turn all off. 3. On circuit breaker panel, turn off all breakers on the top two rows. DP off. Rear Lead. 1. Ind Brake, Auto Brake are set correctly. 2. Open up Air settings and Select Cut-Out and Lead. Save. "Should be Cut-In but if you do it applies brake cylinder pressure and you will not move." 3. On the three "control" switches, turn all on. 4. On circuit breaker panel, turn on all breakers on the top two rows. That includes DP. Rear Trail. 1. Ind brake, Auto Brake, and Air settings are all set correctly. 2. On the three "control" switches, turn all off. 3. On circuit breaker panel, turn off all breakers on the top two rows. DP off. Now that they are all setup, I go back to the lead engine and turn on the Banking Comm. In theory, that is that is needed. You do have to wait until the Rear pressure is close to 89psi before you try to start moving. If you try earlier, you won't move. So at this point, I engage the throttle to 3 and start moving. If you go external camera 3, you can hear the front two engines rev up and off you go. If you move to the rear lead engine, you can see that it's throttle matches the lead. If you look at all engines, you will see the correct Effort shown. BUT....if you got external camera 3, push twice to move to the rear engine pair, you will NOT hear the engines rev. They sound quiet. So I tried this. I restarted scenario and did the lead pair setup. When I moved to the trailing pair. I shut down their engines, as they do not sound on, and powered them back up. You hear them start and rumble, and can see the Engine RPMs climb on the monitors. Then I set them up as the trailing pair. When I moved to the lead engine, and enable the Banking Comm and apply throttle to 3, I went to external camera 3, and you do NOT hear the engines rev. They are quite. But if you camera 3 again to move to the rear pair, you hear them rev and running. DP appeared to work as I could still control from the lead engine. Now for the weird test, I did a normal DP setup and started rolling with lead engine pair revving and trailing pair were quite. I switched to the trail, lead engine and turned off its engine. Then restarted it and verified air brake settings. Went back to lead engine and reset the Banking Comm. Now when I would go external, my trail, lead engine made noise, lead did not. Trailing lead engine made noise, trailing trail engine was silent. So only two of the four engines would sound like they were running at any given time. I have not yet tried to complete the scenario after setting up the "normal" DP setup to see if I can complete it. You have four engines for a reason but if only two "appear" to be running, are you really getting that extra pair of traction? I do not know yet. So I wanted some feedback from others to see if you noticed this weirdness or if you try what I did, get the same result. Thanks.
