It is my understanding that the WDWRR has never missed a day of operation. Is this true?
In addition to the days when the entire park was closed for hurricanes, etc., there was a period of perhaps two weeks when the trains did not operate.
It happened when the 16-inch water line that runs under the track next to the Adventureland Crossing broke. Before it was shut off, it had dug a hole directly under the track about 20 feet across and we're not sure how deep (*I* certainly wasn't going to get close enough to look!)
It took a couple of weeks to dig out the mess, repair the pipe, fill the hole, and rebuild the track.
I tried to convince the Company to run one train in shuttle service, back & forth, but the budget wouldn't allow it, so we just shut down. I had several nice shifts standing at stations saying, "No, not today."
