Nothing to be upset about, just means they are installing the 2nd train. Basically the permanent crane attached to the train storage house will lift each car in to the 3rd storage bay, once the train is fully assembled it is rolled out on to the transfer track and then stored in the appropriate bay. This train will be headed for bay 2.
LOL! The frown was because they put it away and we can no longer see it. You are probably right about the next train to head to bay 2.
