B. & M. R. R. R. Haddam, Kansas in Nebraska

From: "Nyla Stanton" stanton@neb.rr.com

I have a Brass Wax Sealer with the following "B. & M. R. R. R. Haddam Kan in Neb", (Burlington & Missouri River Railroad). I am seeking information as to why it was listed Haddam, Kan. in Neb. Did B. & M. R. R. R. ever have rails through Kansas and specifically Haddam, Kansas, or why is it stamped this way? If so, what time period might this have been?
