The highest cost incurred durring extension of any public transportation extension is right of way. Most who bandy about costs for extension are using public figures that had to include these costs in their figures. Disney already owns the land. Another large one is engineering costs including land studies. Most of the land studies where done durring the early years. Problem is overtime information is filed and forgotten where because those responsible are no longer with the company. Proof of that is the removal several years ago of one of the monorail trains for reverse engineering. Until number crunchers are replaced by corporate executives who look at the parks on a personal level and quit worring about keeping their jobs similar to the auto companies and look at what made Disney legasy great,.The Disney Brothers doing above and beyond, and not just the status quo, nothing will ever change. Problem is that the 30- 50 somethings in charge at the top look at only the numbers because to do anything else might actually make them look at the human cost or benefit without profit. Which by todays buisness standard is outdated, outmoded and might actually make them look at what they did to get to the top and who they actually hurt on their way.
