American Flyer compatibality

What modern manufacturs make trains and cars compatable with my American Flyer 2 rail S gauge? All my cars and locos are original AF, but I may be interested in some items to run without worry.
Thanks
Jim

Currently the big two in American Flyer compatibles are S Helper http://www.showcaseline.com/
and American Models http://www.americanmodels.com/
this site http://www.trainweb.org/crocon/sscale.html is the best S scale site I have found and covers American Flyer, scale, and narrow gauge.
The NASG site http://www.nasg.org/ also has information.
Enjoy

I beleive both K-line and Lionel are makes engines and rolling stock for S Gauge.

Although a functional upgrade is difficult, it should be easy to make two-rail American Flyer track look better by adding a cosmetic center rail…:wink:

Who needs that nasty rail in the middle ;)?
