Oh I praise the days when there were descent manuals for TSW ! Nowadays there's only the Add-On Guide... Fortunately there's a Riviera Line Gameplay Guide. UNfortunately it's of no use. Just a list of available locos, trainings, Scenarios. But wait, here's a link to YT video: "Class 802" Tutorial. And no, the problem is NOT mentioned there. So instead I made the in-game tutorial which told me how to drive the loco but not how to reset after an TPWS/AWS penalty braking. So please if anyone knows how to continue my journey, please let me know too. THANKS! PS. I didn't touch the DRA button of death !
If you miss an AWS warning wait for the train to stop and acknowledge it by pressing the AWS button on the TPWS interface, I think after about a minute you should press the brake release button and you should be able to continue
I made several tests and it turns out that the process is quite simple! keep direction lever in forward power lever to max brake (not needed for the reset, but prevents rolling when it resets!) wait about 50 seconds press AWS button on the upper left panel, where the brake release button is. The brake release button is NOT NEEDED.
