Thanks, maybe I will order that loco now and take a chance.
I have a BLI PRT J1 2-10-4 and an Athearn SD70ACE that run fine through these turnouts with little to no effort. An sd40-2 shouldn’t Have any problem. The Bachmann SD40-2 I had could run on 15” radius which is smaller than the roughly 18” radius of #4 snap turnouts. Just be sure to have the loco run slowly through the turnouts at first to check.
I have my eye on a Scaletrains loco, wonder if it runs better than the old blue box. My turnouts are close together.
My old blue box Athearn SD40-2’s will go through Atlas snap track turnouts if there is some straight track between back to back turnouts like a crossover. They do have a little bit of trouble if the crossover is between parallel tracks that are only 2 inches apart.
I have a switching layout where I run all four axle locos. It is code 100 track with Atlas snap turnouts and no curve track. Will a six axle loco go through those turnouts? I have my eye on a SD40-2 but if it will have trouble I will pass on it.
Thanks in advance
