bigger track

[full maxx]

ok so the train set and the Pere Marquette arrived today and after seeing them in person without even running them I can tell that the 18" radius will be a stretch... the set came with 22" radius so what is the next bigger curve that will allow a double oval and I'm guessing #6 turnouts as the P.M. is quite long and won't take tight curves as are the passenger cars that came with the set...they barely fit on a single piece of straight track with no room for motion

E-Z track comes in these increments:
15" Radius Curved is the smallest and should be avoided
18" Radius Curved is also somewhat limiting
22" Radius Curved is the minimum radius for your set
26" Radius Curved is the next highest radius and should work with #5 or #6 crossovers and turnouts
28" Radius Curved
33.25" Radius Curved
35.50" Radius Curved is the largest
