the U.S.A. was "Number One" in "high-speed railways" back in the 1960s, it isn't a leader any mo ...

Here's the Wikipedia entry on high-speed rail:

Multiple definitions for high-speed rail are in use worldwide.
The European Union Directive96/48/EC, Annex 1 defines high-speed rail in terms of:
1. Infrastructure: track built specially for high-speed travel or specially upgraded for high-speed travel.
2. Minimum Speed Limit: Minimum speed of 250 km/h (155 mph) on lines specially built for high speed and of about 200 km/h (124 mph) on existing lines which have been specially upgraded. This must apply to at least one section of the line. Rolling stock must be able to reach a speed of at least 200 km/h (124 mph) to be considered high speed.
3. Operating conditions: Rolling stock must be designed alongside its infrastructure for complete compatibility, safety and quality of service.

The International Union of Railways(UIC) identifies three categories of high-speed rail:
Category I – New tracks specially constructed for high speeds, allowing a maximum running speed of at least 250 km/h (155 mph).
Category II – Existing tracks specially upgraded for high speeds, allowing a maximum running speed of at least 200 km/h (124 mph).
Category III – Existing tracks specially upgraded for high speeds, allowing a maximum running speed of at least 200 km/h (124 mph), but with some sections having a lower allowable speed (for example due to topographic constraints, or passage through urban areas).

A third definition of high-speed and very high-speed rail (Demiridis & Pyrgidis 2012) requires simultaneous fulfilment of the following two conditions:
1. Maximum achievable running speed in excess of 200 km/h (124 mph), or 250 km/h (155 mph) for very high-speed,
2. Average running speed across the corridor in excess of 150 km/h (93 mph), or 200 km/h (124 mph) for very high-speed.

The Acela Express runs in "high-speed" mode only for 45kms of the route. The rest of the route is below the minimum speed required for "high-speed rail" as defined above.
