Does anyone know what the superelevation limits are for the Acela trains on the Northeast corridor routes? I'm going to guess up to 6 inches actual, and 4.5 inches unbalance? Also, I'm wondering what the top speed limit is for the Acela trains.Thanks!Mark

Well I'm not sure about the superelevation but I can tell you that the Max Authorized Speed for the acela is 150 mph. AEM7AC 920

Thanks! I guess I should add that I'm also curious about the same data for other high-speed lines around the world, like in France, Germany, Japan, etc.Mark

It depends on the desired speed-limit and the curve degree. A 6-inch superelevation would be good for 90 MPH on a 1° curve, or 45 MPH on a 5° curve.I don't know much about prototype track construction though.

I just mean what is the maximum allowable superelevation, regardless of speed. I did some scrounging on the web and found that in the UK, it is 6 inches actual, and 4.5 inches unbalance. I also found that for the tilting cars, like Acela et al, generally there is more unbalance allowed, but I couldn't find what that increased number is. I read somewhere that some swiss trains allow up to 11.8 inches unbalance. This would mean they could do a 1-degree curve at 160mph or a 5-degree curve at 70mph (assuming both curves had 6 inches of actual superelevation). Thanks for your input, this stuff fascinates me!Mark
