I posted this in the main TRON thread, but in the updated concept art we received on Thursday, we can now see what Disney's plans are for the WDW Railroad and (maybe) Speedway.
As we can see, the Railroad will still be going under the TRON canopy, but now through a dedicated tunnel. I would imagine the tunnel have some type of projections or screens, along with narration. This will probably also suppress any noise coming from the trains to keep the TRON area as quiet(?) in a way.
As for the Speedway, it is not shown in the new concept art. Now I believe this is just a placeholder as Disney will probably reveal their plans for it down the road. The evidence of trees/shrubs in its place is just to shine away focus from it...for now.
(again old concept art on bottom, new on top)
