N&W in 1903 -- New Rail

[NW Mailing List]

Ed,

The following is from the 1955 Railway Track & Structures Cyclopedia, p. 270, and seems to imply the answer to your question:
  Similarly, in 1946 these design principles were applied to improving the 152-lb PS rail, which had been in use by the Pennsylvania since about 1930, and, as a result, the new 155-lb PS rail section was evolved.
The design principles referred to above involved taking some metal from the upper corners of the rail head to deepen the head and to strengthen the upper fillets of the web.

  For many years the Pennsy standard was a 152 pound section.  Does anyone know if and when they went to 155 pound rail?  I think they were still using the 152 pound section after WWII; when was the 155 pound rail put in on the Tadpole?

    PS is an abbreviation for Pennsylvania Standard - one of 
    several types of rail.  Compared to RE (for American Railway
    Engineer Association)  rail, it has a shorter web and
    a heftier head.  N&W tested a six- mile section of the
    155# PS rail in the west main track near Glenhayes, WV on the
    Scioto Division.  In the 70's, it was taken up, cropped, welded,
    and re-laid on the Buchanan Branch.
