While technically a high speed 'regional' metro(like the ones China has been building) does have a top speed of 160km/h, it is more like regional rail than a 'lowest tier' urban transit.
Most metro systems have a top speed of 80km/h due to station spacing and physics (motor gear ratios tuned for accelaration).
That or you are talking about the Keisei Skyliner, which is an Airport Express service.
My nearest lowest tier rail bound mass transit system is the S-Bahn Hannover which uses Stadler FLIRT XL 3 at a top speed of 160km/h, yet they only serve Hannover and its immediate surroundings.
This is also the case with the S-Bahn Bern (using Stadler KISS), parts of the S-Bahn Rhine-Ruhr, the S-Bahn Bremen, S-Bahn Mitteldeutschland (Leipzig Halle), S-Bahn Dresden, S-Bahn Zurich and Wiener Schnellbahnen.
If you live near a big(ger) city in the DACH Region but not directly in it (meaning out of range of its Tram system) this is absolutely not uncommon.
