Is it only in a topsy-turvy world that the same name may mean different things? If you want to know...

Just how does a railroad locomotive come to be named a Mikado? "The first locomotives of the Mikado type were built by The Baldwin Locomotive Works in 1897, for the Nippon Railway of Japan."

Later models ran on the banks of the old Raritan,

could be found on the Atchison, Topeka and the Santa Fe,

and maybe even as the Chattanooga choo-choo.
