The standard tie spacing on centers was 19-1/2" for main, heavy branch, switching, and engine running tracks; 21-1/2" for light branch, switching, and engine running tracks, and heavy passing sidings and yard tracks; 23-3/4" for light passing sidings and yard tracks, and heavy industrial, shop, and storage tracks; 26-3/4" for light industrial, shop, and storage tracks; and 30-1/2" for station sidings, unimportant spurs, etc. (L-168, 1946)

Standard ties measured 9"W x 7"H x 8-1/2'L (L apparently minimum, not nominal).

Switch ties measured 9"W x 7"H and were cut in 6" intervals from 9' to 16'L . Headblock ties varied from about 11-1/2' to 14-1/2'L, depending on the machine.

Bridge ties measured 10" x 10" x 10'L (or longer where needed) on 15" centers. (L-50, 1943)

  Hi folks
  Can somebody tell me the standard tie spacing on N&W  130lb rail please together with actual size of N&W rail ties. I am trying to do a small TT scale project with handlaid track and need sizes to get it right. I have ordered some drawings from the archives but I am too impatient to wait for them to arrive in the UK

  Thanks and regards
