Privatising the Postal Service is an ok idea, anyone can do that job (eg. FedEX, UPS, etc). Privatising Amtrak is a different kettle of fish, it is a natural monopoly on critical infrastructure. In that situation prices will go up if private investors buy it. Increased freight costs will inevitably be passed onto consumers. Anything privatised like this (eg. electricity transmission lines) has been shown to be a net loss for consumers.
