I have read alot about the building and troubles encountered buidling this RR, but I don't recall ever seeing a dollar amount of what it costs (maybe the true cost was never known as a semi-public works). I know there was alot of gaft, corruption and bribery going on which upped the cost, but haven't seen an estimate or a wild guess at costs.
Reason I ask, is I have been reading some publications lately where light rail and RR are putting down new track and the cost is somewhere north of 1 million per mile. So wondered if you scaled up the transcontinental cost to today's dollars would it have been close to 1 million per mile to build?
