Recent news about the funding for the Brenner Base Tunnel led me to this informative site, but I cannot interpret the gradients. They are obviously expressed differently from U.S. usage. Would somebody scroll down through the page to fourth section, which includes these lines:
Average incline in the BBT will be about 8‰. This is well below the maximum incline of 12.5‰ for high-speed cross-border operations provided for in the Council Directive on TSIs (Technical Specifications for interoperability).
