Thanks.
I see why Im getting different answers.
Some people measure to Ties, some to inside track and some to Center line of track.

Thanks, I like the idea of using the center line of the track.

I'm looking for the Track layout Dimensions for the BIG HAULER, Polar Express & White Christmas Sets Large Scale Track.
or the dimensions  of Length and Width of the OEM layout.
I think it around 47" by 64" but would like the actual specs.
I'm making plywood platforms to put the track on.

So I would like the Inside Radius and Out side Radius of the Track Turns and Length.

Thanks,
Gary
