The fact that WDWRR crew is under Main Street Ops has absolutely nothing to do with the incident you’re referring to. The engineer in the video was in training and it was probably her first time dealing with wheel slip. She’s coming out of Fantasyland station, which is the only grade on the line, and it looks like it had been raining, which means the rails were more than likely wet. Not to mention it doesn’t have to rain for the rails to become wet. Moisture in the air from humidity, which is abundant in FL, can cause it. Anyway, add in the fact that none of the locomotives have sanders, and yeah you’re gonna have a good chance of slipping coming out of Fantasyland Station. Heck, I’ve even seen some of the veteran/old timer engineers slip on the grade. It happens. But to say that it happens because the WDWRR falls under a certain department? That’s a bad take.
