Just started playing Sherman Hill on TSW3 and I'm doing scenarios. Yesterday, during Switcheroo, I dropped off a rake of cars in the yard, and after uncoupling, the locomotive shot backwards at 50mph, as if fired from a cannon. I didn't have the recording set up, so all I can show is a screenshot of the speed graph. As you can see, it went from zero to fifty instantaneously. I was lucky that the shot was along the track, and I was able to brake in time before hitting something, and complete the scenario. This morning, I started Magnet for Trouble. Look what happened when I uncoupled from the other locomotive. I got it on video this time.
