Paul identified these as Endo models from the logo on the bottom of one of the cars. He also knew that these models were of Hankyu Railway cars. Once I knew the name of the railroad and of the model company I was able to find out more about it on the web.
The Hankyu Railway is a non-JR private railroad that operates several lines around and between the cities of Kyoto, Osaka, and Kobe.
This photo is of a Hankyu 6300 series train which is the closest to the models I have.
From what I read on the web It seems that these had been in service from about the mid 1970's and taken out of service about a year ago.
