Re: I thought high speed rail didn't use steep grades on short segments precisely to avoid the rollercoaster effect

But if CAHSR is using short grades in the 2-1/2-4% range, which is clearly the case in Fresno, but also it appears in Hanford, then it must not be high speed rail. Or do I have this wrong? The whole project is designed for equipment that runs 200 mph, not 125 mph.

  Rumor was CHSR would poison pill the segment by building to standards that can't support the weight of traditional diesels or dual modes But 4% grades are not a problem 08-03-2023 - 19:46
