Wow. Think DTG need to sort it or tell EMD that they've also accidentally made an express passenger locomotive.
Been that way since the physics update last year. If you keep the amps reasonable when powering up, as a real driver would. I find the speed doesn't get out of control. On a German loco such as the BR155 for example, it wont accept sustained high amps. The throttle drops off. Maybe the 66 should be doing the same?
