What is the min curve track one of these can take.

What is the engine? Post War versions will do 031. Modern scale ones require larger curves, likely 042-054.

Polar express. Bought it without track

O-36 is what the set comes with, so count on that radius and larger. It MAY navigate O-27 but it very well could bind up the drivers.

The Polar Express sets are rated for O31 curves.
