Talk:double crossover

different crossover types
I believe our definition here is incorrect, or of a rare usage. In the rest of the railroading world, a double crossover is two separate but adjacent single crossovers which do not overlap to form an "X". A crossover which does so overlap is often called a scissors crossover or diamond crossover. See crossover (rail).

A picture being worth the proverbal thousand words, here's my interpretation:

===**===========**===       ====**==**====           \\         //                 \\//            \\       //                   XX             \\     //                   //\\ =======**===**=======       ====**==**====         double crossover           scissors crossover, diamond crossover —scs 17:52, 19 November 2006 (UTC)


 * Thank you for the comment and the great ASCII-art pictures. I fixed the definitions a bit (only 13 years later) ... now:
 * "scissors crossover" = "diamond crossover"
 * "scissors crossover" and "diamond crossover" are hyponymes to "double crossover"
 * Further comments appreciated. Taylor 49 (talk) 10:46, 14 August 2019 (UTC)
