  • Russ Simpson writes: the Oct 1913 SR&RL RR drawing for their Standard Turnout with #9 frog (available from Robert Schlechter and Gary Kohler), shows the ties were 6×6 with lengths within the turnout from 5-3 to 7-10. A tie before the throwbar ties was 5-0. The two throwbar ties were 7x9x11-6. Tie spacing varies between (most commonly) 19 to 21 center to center through the turnout. 
  • Terry Smith writes: the September 1913 B&SR RR drawing for their Standard Turnout with #8 frog (which was supplied by Gary Kohler), specifies ties which were 6×6 with lengths within the turnout from 5-2 to 7-10. A tie before the throw-bar ties was 5-0. The two throwbar ties were 7x9x11-6. Tie spacing varies from 15 to 21 inch centres through the turnout, with 20 inch being the most frequent spacing. Of interest perhaps to model railroaders, the drawing specifies the radius of the curved switchblade as 226 feet which scales out to a radius on centreline of 68.25 inches in 1:48 scale.
