I got in line for MF around 4:30 pm. Soon after, they put the blue train on the transfer track and there was a long pause during which they weren't running any trains. Then they started running the red train only. Around a half hour later, they started running the blue train and the red train together. Around an hour later, they took the red train onto the transfer track, and there was a longer pause during which they didn't run any trains, it seemed like almost a half hour. Then they started test runnign the yellow train empty. I dont' know about the third hill, but it BARELY made it around the last hill coming into the station. Then they ran it with a crew member, then they loaded it and ran both the yellow and the blue trains. I rode the yellow train, and it was the first time i rode Mf so I can't compare it to the other trains, but boy that is one sweet piece of machinery.
