Yes, even before covid, it seemed like they never put any thought into what to do about the railroad during Tron construction. Seems they could have developed a plan to keep it going and only have to shutdown for safety reasons when those large cranes were moving track pieces into position.
It used to be a great way to get from the back of the park back to the front and exit. Clearly, covid made the Tron construction take longer, but there was never a good plan relating to the railroad.
