Alan,
Florence & Cripple Creek is only the road name.  I has been used in nearly every scale & guage.  What are it's measurements?  What kind of detail does it have, ie; metal ladder rungs & hand holds etc.  Also can you post a pic?  But the measurements will tell all.  I think it is a 1:22.5,  20 foot boxcar.  They will look small behind a Ten-Wheeler.
