K-Line track: O27 only?

[phillyreading]

K-Line made 027 and O gauge track, some long sections that look similar to Lionel except for tie spacing on the O gauge straight track. K-Line also made S gauge track. Lee F.

K-Line made both O-27(brown ties) and "O", plus "O" ShadowRail, and "O" SuperSnap(all 3 are black ties).   "O" items are catalog #3xx, O-27 items are catalog #2xx.  Both Lionel & K-Line made long straights - 36" and/or 40".

Sorry for the simple question, but...

I'm looking for some 40" O (not O27) tubular straights.  I keep seeing K-Line track on eBay.  Did they make both O and O27, or do I give it a pass and stick to Lionel?

Thanks.
