Bachmann EZ Track ?s - Model Railroader Magazine

Go to Bachmann trains and navigate into their track and accessories.  Their turnouts are listed there.  Note that the N. American turnouts are not meant to fit on a curve most often.  So, their diverging routes are actually straight, unlike British ones that are curved.  I used the longest angled frog turnouts that Bachmann offered a year ago, and they work out to about a #5.5ish, maybe a bit more. However, they cannot be substituted into a curve at any point and maintain the original radius.  The curve will run straight for 5", and then you can commence adding more curved pieces.

Shinohara makes a Code 83 #7.5 curved turnout where all possible exits are on a radius.  I have several of those, and they are nice turnouts.  However, I had to bash mine a bit, cutting up the tie joiners so that I could increase the radii by about 2" to get them to fit with my broader curves.

Bachmann now offers higher numbered turnouts, and curved pieces that will allow at least 30" curves.  Previously, all I could manage was 22".
