We go over a #10 turnout. Forgot to tell you in vid, this frog is a rail bound manganese frog. Also, there are different types of frogs, this one is a tangent frog. Also, the length of the turnout is dependent on the frog angle. Most common turnouts in freight rr are the # 6, 8, 10, 15 and 20
Aplogize, RE does not mean relay. It stands for American Railway Engineering Association.
