Countries with public rail systems (or railway companies that are largely owned by the state) are usually way better than privately operated railway lines. Private railway service almost always sucks (crappy trains, high fares) and is only profitable on the most popular routes.

Toll Roads? Generally better maintained and provide a shorter pat for a small but willing-to-pay segment of the population that government programs overlook.

The M6 toll is a pretty nice road as roads go. I believe it was privately funded.
