N code 50 and code 80?

[pamardon]

what does suppose to mean??
is atlas a good product?

Code is basically the height of the rail.  Code 55 is smaller than code 80.  Engines or cars with large wheel flanges may not run well on 55.  (An FYI - check HO gauge track.  That usually comes in code 83 or 100 - you will see the difference.)

Atlas makes an excellent track & other items in N.

The "code #" for model RR rail is the height in Thousanths of an inch.
Multiplying by 160 (scale ratio) gives prototype size represented.
Code 40 = 6.4" Code 55 = 8.8" Code 83 = 13.3"
I am not aware of code 80 (12.8") rail

Yep - that is correct - Atlas makes code 55 & 80 track in N.  I believe their Tru-Track is code 65 .

code 55 the rails are 55mm tall
code 80 the rails are 80mm tall
check out Peco track it is a little pricy buy you will not be disapointed

Gepetto62,

As Pamardon mentioned, I think you mean:
code 55 = 0.055 inches tall rail only
code 80 = 0.080 inches tall rail only

note 55 mm = 2.17 inches, 80 mm = 3.15 inches.

In the case of Peco, the exposed rail is what counts, as both the 55 & 80 are the same overall rail height, the 55 has an extra flange and is embedded in the rail only exposing 0.055 inches.

 Yes. And basically the shorter rail is more prototypical and for the more advanced modeler than the taller rail.
