Les, a Shinohara (Walthers) #8 is 14" long. Either they or Peco also have a #10, but I don't have one on hand to measure. I'll second Russ' comments on the respective tolerances at the frog. The two #8s which I have, and evidently some #10s yet to come, are unused cast-offs from a friend who's currently building a layout. He discovered the sloppy frogs when he ran a train through some recently completed trackwork, and discovered that the semi-scale wheels which he uses react rather poorly to the loose tolerances. He's replacing them all with Pecos (and helping to move construction of the second level of my layout a little closer).
