Nickel silver track with gray roadbed; 6 per card.
17.50" Radius Curved Track is best used to make wide, sweeping curves. This track accommodates longer locomotives and rolling stock, and permits mainline operation at higher speeds. It can also be placed on the inside of 19" Radius Curved Track for excellent double-track mainline realism. The 6 pieces of track in this package make up one-eighth (45 degrees) of a 35" diameter circle (a full circle is 360 degrees).
