Starting around 1960 Trains started listing top speeds on rail lines. Interesting to see those numbers. I am skimming the June 1966 as I type this. I should have mentioned this the first time the list was published. Given the legal complaint against NS re: Crescent it is worth noting the old SR was topping out at 65 MPH versus other RRs hitting over 80 MPH, and it was not for many miles at 65 MPH.
