To respond to some posts above, asking where private-sector dollars could be used:
1. Real estate:
2. Fleet acquisition:
3. Contracting out entire routes:
4. Contracting out certain on-board services:
5. Contracting out infrastructure improvements:
6. Total route re-dos:
1. I think that would be good but I don't think Amtrak owns much real estate around its building; probably dosn't own many of its buildings (often owned by the railroads); or its buildings outside of a few are not in nice areas or are surrounded by railroad property which Amtrak doesn't own. Given they had the money, they could use eminent domain to take land for the site of a new station plus the land around it and then partner with someone or develop it themselves with private help. However, Amtrak is a company known for its Amshacks so that idea looks bleak.
2. Leasing cars would be a good idea if economically feasible IF Amtrak could make more money than the lease and maintenance costs so e.g. leasing a sleeper car that brought in more additional bucks than it cost would work.
3. Given that Amtrak could write and enforce a contract that required better service, did not burden passengers with higher costs and protected employee rights, IMHO, is beyond them because there might be issues with host railroads, insurance and liability, and enough of a profit incentive for the lessee
4. As to services, this might also be a possibility if they could write a good contract but Amtrak seems to not want cooperation with third parties. Witness I.P. who apparently wanted a Chicago-NYP tie-in to get riders who would likely be willing to pay for higher level of amenities and Amtrak's crushing of Private Varnish.
5. Big projects are contracted out because Amtrak gets big bucks for them on a one-time basis. But with no guarantee that Amtrak would get long term funding to slowly pay off the bill, any kind of multi-year maintenance push onto private industry would probably be very risky for private industry as even floating bonds to pay a contractor to do the work instead of leasing it out.
6. Politics has always interfered with transit systems using this approach. Wouldn't it be great if a transit system were to secretly come up with a plan to expand a route, then buy up the property cheaply around its proposed stations before the announcement of where they would be, then lease/sell/develop that property to pay for the transit? Fat chance! Amtrak and transit systems get money from the government so the legislators want to enrich their friends instead of saving the taxpayers money. And government agencies including Amtrak can't keep secrets. Private companies can because they want to enrich the executives and they can squeeze local governments by promising or withholding stations to make them fight each other for the spoils.
If only it were a real possibility instead of a fancy.
