The ride warehouse building goes backstage, in an area that is currently occupied by a big warehouse and rehearsal halls used by the parade/entertainment groups. They are building a new parade building nearby on land currently used for an empty warehouse. They are getting really good at moving support facilities off property at Disneyland. They now even make the horses for the Main Street Streetcars commute in from a ranch 15 miles away, so they could build Star Wars Land.
From the Disneyland forum here, and with thanks to
@truecoat for doing this, here is the DHS footprint of the building overlayed on the existing warehouse just north of Toontown that is to be torn down for Runaway Railway. There is plenty of room here for the Toontown version, although Toontown itself will be reworked for the entrance to the ride.
As a longtime observer, I am convinced most park execs on both coasts are incapable of playing 3D chess. Checkers they can handle, but 3D chess they just don't have the capacity for.
They can only really plan about 90 days out, and 30 days is their comfort zone. They are mostly reactionary when given information by other people, in this instance a WDI organization who simply had to admit they can't get Runaway Railway open before this August.
While you may need to move some personnel around to help Star Wars Land, which is the more important project, I am suspicious of the new narrative that everything is fine with Runaway Railway they just need more bodies working in Star Wars Land for now.
I have a sneaking suspicion that the wireless/trackless ride systems that WDI went headfirst on for both Runaway Railway and the Star Wars Resistance ride are the real culprits behind all the delays and drama. The wireless/trackless ride system just isn't ready for prime time, and now they are forced to open Star Wars Land on both coasts with only the Millenium Falcon ride operating, and open Star Wars Land in DHS eight months before Runaway Railway is ready.
It's a recipe for crowd control and PR disaster on both coasts. And even mediocre checkers players like they have in TDA and TDO wouldn't do that on purpose.
In short, they are totally hosed on both coasts this year.
