Amtrak, which has never made any money – and has, in fact, required subsidies for all of its surly, customer-unfriendly life – is now proposing to spend about $150 billion to make it possible for riders to go from New York to Philly in under 40 minutes.  Which is about how long it takes for passengers to get online using the WiFi currently available on Amtrak’s flagship Acela trains.
