Buckycatt1, most steel mills around here have switches that are number 4 and smaller, an SD of any kind would not be allowed in the mills . It should make it through a number 4 turnout, but number 6 on the mains would be the minimum I would use. Give us a better idea of your steel mill plans. Around the electric furnaces in the mill I used to haul fly-ash the turnouts were very tight. I never measured them but I would have bet on a number 2 not being impossible.(The locomotives they used were GE 70 tonners) Perhaps Wayne can weigh in here.
