The tag highspeed=yes indicates that a railway track is part of high-speed rail.

Germany

The list of German high-speed rails can be found here(de) and (especially for newer tracks) here(de). The conditions to consider a track to be high-speed tagged with highspeed=yes are defined here(de).

United States

Amtrak's Acela service with speeds up to 150 MPH (241 km/h) in Massachusetts and Rhode Island is tagged highspeed=yes as its underlying infrastructure, the Northeast Corridor, a complex four-track system, upgrades. As of 2018, OSM improves this, keeping the Northeast Corridor fully updated is a medium-term goal of OSM-US. The Northeast Corridor's maxspeed=* tagging is somewhat fluid, though appears largely accurate. Several "higher-speed" corridors can be found in our Amtrak wiki where regional (as boldface type) signifies such corridors and regional (as regular type) signifies a 90 MPH (145 km/h) corridor (Class 5 track). Amtrak says nearly half of its routes have 100 MPH (161 km/h) segments, meaning there is some Class 6 track where Amtrak offers "higher-speed regional service," allowing 110 MPH / 177 km/h for both passenger and freight trains. USA high-speed rail and how OSM tags and wiki-documents USA high-speed rail improve, though comparatively slowly.

Imported into OSM in 2007-8 were public domain federal government rail data which might be characterized as "noisy though usable." These (TIGER) data do improve and after a decade are in an earlier-to-moderate state of continuing development. The USA has many definitions of "higher-speed" as this emerges between governments, railroads, rail technologies (e.g. rail-car producing companies) and others. OSM rail tagging conventions encourage a catching-on trend to use maxspeed=*, as it either conveys track maximum speed or remains undefined. ORM provides a simple radio button to display this tag as a map style. Higher-speed corridors emerge along with several regional rail networks that are both forward-looking (non-existent, though seriously planned, or are now being built as is California High Speed Rail, up to Class 9 track — 220 MPH or 354 km/h) as well as actual track upgrades (regional as Class 6, some Class 7 and Class 8 track on the Northeast Corridor). Amtrak's regional services take advantage in several places, this overlap is intentional as higher-speed corridors "knit together." OSM is in a "wet paint" state: USA rail data may be considered in an earlier stage of improvement (as of 2018) as tagging standardizes and wiki documentation strengthens. More consistent syntax is used as TIGER data improve, OSM community builds with more accurate tagging and statewide /Railroads wiki show color-coded status tables with relation links, both succinct and agreeable. Roughly a dozen of 50 states have such wiki, documenting at-a-glance how "green" (complete and correct) are OSM's USA statewide rail data.
