Re: Recent derailments - NTSB says Metro North too fast for curve 82 MPH

ATS/ATC is not required under 80 mph for passenger. The ATS I am familiar with would not provide any restriction on a clear signal, though inert inductors are sometimes placed before certain subtantial restrictions.

I don't believe there are too many systems that enforce speed limits, just the any restrictive signal indication. I believe that PTC is supposed to enforce speed limits and automatically brake for approaching speed restrictions as well as signal indications and limits of authority.

With all the politicans already involved, this pretty well kills any chance of an extension for installation of PTC at least on commuter lines.
