? "O" to "O27" mating pins?

Not only would I,I did!

This is all O27 profile track with O35 Marx and larger Lionel curves as well as the smaller loops with O27 curves.

It works just fine.

Yes but brought back by a person looking for the same answer just a few days ago.

I also agree with others that O-27 track is a fine track system to use. I have made many layouts with O-27 wit no proublems. and to me the 5122 and 5121 switches where some real good switches.

Sorry, but that’s a very broad & patently false statement.

There is no virtue to “O” that makes trains run better on it.

Also most track today has the height of O-27 ( I’m talking actual rail height not track height ) The only problem is finding O-27 track with a wider radius than O-27 or O-31. Yes it was made in 42" and 54" radius and I believe they even did some at 72" radius but all those are not easy to find as to my knowledge they stop making it in either late 60’s or early 70’s

Al you really need to learn facts about something before you start throughing out false statements.

As a little proof for you here is a listing for 54" radius O-27 track

The layout video I posted above is 27", 42", 54", & 72". All of the large radius is new K-Line & Lionel made since 1990. The switches are 42".

Rob and RT,

Rob Is correct. All my track is after 1990. Same here and add in the Marx 34" or 35’R or what ever you want to call it.

The fact is you can hook Ross switches into O27 profile with less issues than O-gauge “High Rail” (that looks very un-real) track. The rub is, all O27 is being dropped off the build list from those who made it. So in the end of the day, would I do it again,NO! Do I like it ,YES!!! Am I glad I have it? YES I AM!!!

Next???

Kevin thanks for the info on it was still being made. I was not aware of that. But my point was that it is out there and there is radius for O-27 other than 27"

Printer65. Like Kevin would I make a layout of O27 probably not. Is it a good system yes. But you asked is it better the answer is no. Is O better than O-27 I would have to say yes. But then you have so many other systems out there also. The main question do you want a track system look’s correct or a track system that will do. O-27 is a system that does work. And if I was going to use it I would use just O-27 or just O gauge track not a mixture. Can you mix them? yes. Just most wouldn’t, because of the difference in height of the two. I personally have more O gauge track than I know what to do with as I probably will never have a layout again, because of lack of room in this house. I also have enough of the gargraves track than I know what to do with. Same story no room.

Bottom line use what you want. it all will work. And about 99% of the engines you can own will work on it as long as you have the correct radius track. The only engines you might have a problem with is ( and most of these will work on O-27 too. ) is some post war engines that are specifically for O gauge track as they have bigger flanges.
