Class A speed limit in passenger service

[NW Mailing List]

Louis,

Thank you very much that is helpful.  Sometime when I have time I will have
to calculate how many inches of underbalance N&W allowed on the passenger
trains vs. the Class A's compared to current FRA requirements for
super-elevation in curves.

Thanks again,

John Rhodes
