Rail Chief Pass Car Question

I am in the market for a set of Rail Chief Passanger Cars #51201. Before I purchase a set and make a major mistake, could someone please provide me with radius this set of cars needs. Thanks Mike

Hello Railfan ! The Railchief Passenger Cars need track of at least 72’’ radius in order to go around corners.

Radius, not diameter?

Thanks for the info Keith. I had a bad feeling that was an o72 set. I only have o54 on my layout.

The Railchief set runs on a 0-72 track curve. 16 sections make a 72" diameter to the outside rails. Not 72" radius.
