@Tom Stoltz posted:@Mikeaa posted:According to SHS, the original SHS track uses a code 131 rail size that was chosen, "because it corresponds to a size of rail used on real railroads, yet still allows operation of AF and AF-compatible wheels." So it's supposed to be compatible, but there may have been some variety in flange sizes. I haven't gotten any of the MTH track to compare, but it should be the same rail size. Hopefully, someone who runs AF on SHS/MTH track now will chime in to give some first hand experience.

SHS & MTH rail is the same. See attached .pdf

Hey Tom,
A lot has happened since I made that statement about 6 years ago! I got my MTH flex-track and it is identical to SHS. The only difference was in less packaging materials - a whole case of 24 pieces of MTH flex track takes up less space than a box of just 6 SHS. Since then Fox Valley has also come out with Flex Track which has the same rail size as MTH/SHS.
