Bachmann Wheelsets?

[Jake]

Hello again all. I was watching an NMRA turnout standards video (made by fast tracks) and at one point, the narrator of the video was talking about two types of wheels, code 110 (meaning the wheel tread is 0.110" wide) referred to as "full scale" and code 88 (0.088" wide) referred to as "fine scale" wheelsets and that the small difference of 22 thousandths of an inch, can make a big difference at the frog. Now comparing a wheelset to bachmann code 100 rail, the look to be a bit smaller indicating that they are probably fine scale wheelsets. Am I correct in this inference?

No.  The code 100 rail refers to the height of the rail, not the width of the railhead.

Jake,
With those dimensions he was referring to wheel not just the wheel’s tread. What he referred to as "full scale" the NMRA term is Standard Scale

Check the wheel and wheelset dimensions in the following
http://www.nmra.org/standards/rp25.html
http://www.nmra.org/standards/S-4_2ScaleWheels.html
Note some dimensions must be calculated from those give in the table.

Proto and Fine Scale wheels are found in

Bachmann wheels --  Standard Scale

No.  The code 100 rail refers to the height of the rail, not the width of the railhead.

I know, I had to put the wheel on the track vertically so that the flange was on the railhead, and th tread's width of the tread was comparable to the height of the rail.
