I believe that this may be IVES pre 1929 becasue of the four cross ties.



Obverse  4 Tie bars vs 3 for Lionel
 Reverse


Note the stepped tie bar
The tie bar is also tapered


027 Curve
 Straight Section

See also this page http://www.railwaypages.com/index.php?t=2&id=17&p=3 for a 1 gauge example with 4 ties.

Chuck has been very help ful with his communications and his web site is an excellent resource.
Charles Cooper IVES

According to a friend on the forums:
"... I was told that American Flyer made this track because they were having too many complaints of the engines flying off the curves."
In fact, it seems that several manufacturers used sloped or stepped rails around 1930.

Further information - this site:  http://en.allexperts.com/q/Model-Railroads-2372/2008/11/Sloped-Banked-3-rail-1.htm shows a photo of extremely similar track having the same stepped ties. It does not however show how many ties there are (3 or 4).  The site's track is American Flyer "20's through 40's", which although helpful and intriguing is neither completely conclusive nor definitive

IVES

On July 31, 1928, Ives was purchased by Lionel and American Flyer
In 1930, Lionel bought out American Flyer's share in Ives
Lionel dropped the Ives name in 1934 and although re-issues were occasionally made, the Ives name never re-appeared on the marketplace with any kind of regularity. (Wikipoedia)

Lionel O27 - Korean Era ? - Grey or Plated Silver Colored Tie Plates

I don't know if these are different years but suspect that the plated versions (looks like chrome) are 1960's

All three verseions are nearly identical except for the color of the tie plates and number of holes




Straight and Curved Sections
Light weight tie plates with one hole each


Straight section is 9" long
Curved section is 10-1/4" long


Profile
Chromed tie plate top (two holes). Grey tie plate bottom (1 hole)


Obverse with name stamp - color balance is off due to camera

Meccano Clockwork 2 rail. Possible Ca 1920

Overview
Closeup of name
Meccano England
Closeup of the name. the O is poorly stamped


Rail Height
Mounting Hole Placement and "England" at the Right
Rail Width English
Rail Width metric
Rail spacing is 1-13/32"  Seems wierd ... let's try a metric ruler
Rail spacing is exactly 35 millimeters pointing toward european design
