Did they just pull the cost out of their behinds or something? $800,000 seems on the low side, especially with the artists rendition they have. I realize that labor might be cheaper there.
Still - one of the comments was someone mentioning the Lancaster, PA station and Amtrak's demands. However, that's a staffed station, so they're going to want certain standards before they commit to paying employees to be there. And wasn't there an issue with the length of the bus bays?
Lancaster PA is also a much larger station which apparently had a substantial backlog of repair & refurb work with 529 thousand passengers in FY2014.
West Wendover is presumably going to get a 550' long 8" ATR platform which is the standard for the western LD train stations have gotten new ADA compliant platforms in recent years. Unless the platform is off on a siding, it won't be 15" high which is the floor height for the Superliners. So the station will either need to store a long bridge plate or a movable wheelchair lift.
West Wendover has a 2010 Census population of 4,410 so this won't be a busy stop. Elko, NV with a town population of 18K in 2010 had 9.426 passengers in FY2014. Unless it draws a lot of casino traffic, the West Wendover stop is likely to add a couple of thousand passengers to the CZ per year. Still, a couple of thousand new annual customers.
