If you would like to know my source, I'm fine with that. I actually work at Magic Mountain. Not all rehabs take that long, but that is the average. I know over those weeks the trains are not being continuously worked on. Apocalypse took so long to get the second train back because it kept getting put off because of other projects. Coaster trains are a bit more complicated than a frame with wheels. There are a lot of small sensors that have to be aligned just right and a lot of time is used to adjust them properly. Also, some of that time is spent waiting for parts.
