Actually that was a result of the mechanics trying to get the train home... They split the train in half, pulled half of the train through the loop, followed by the other half. Then the train was reconnected and sent on its marry way. When it did get stuck in between the loop and cobra the good old loop brakes decided to grab the train at the last second on the return trip slowing it down enough not to make it home! The computer just had a good old premature ejaculation. And yes that did happen twice it’s the curse of the name.
