Sometimes when I'm going to stop the train will just fly off the track, and it's done this several times.
This with an unfitted train? (Non braked consists grey mineral wagons), if so it's way over sensitive! I can tap the brakes from 5 - 0 & boom derail!
Gray wagons have no brakes, red wagons do, DTG have (probably by mistake) configured the consist to have the red braked wagons in the middle of the train & the gray wagons at the front thus the brakes are not used on the entire train apart from the loco, this setup in TSW loves to derail no matter how hard you try to brake carefully. So a non braked hence the term unfitted.
