So the lift hill track is confirmed 286 feet tall from station to peak?
295-286 = station track 9 feet off the ground... something isn't adding up, is it?
Looks like the track is around 17 feet of the ground assuming standard size doors (80 inches tall). They will obviously be doing doing some grading and evacuation etc. for the station to take that ground a little below the station sea-level elevation shown on the plans.
286+17 = 303 foot lift hill.
I don't think you can simply calculate from the sea-level station ground numbers to the sea-level lift hill height as, like I said, they will be evacuating the land for the station by a bit, maybe a few feet.
It makes zero sense that they would invest millions into this project and leave it at a 295 etc. foot tall lift hill instead of going ahead and making it an even 300 (or more) for marketing purposes.
