Jimmy and Lynn,

Thank you for the information. Was the switch in name of aspects done
around the time of the Virginian Merger? Or as late as the 64 take over of
the Nickel plate, Wabash and other assorted roads? The farthest back the
rule books I own go is 67.

Thanks again for the information,

- Brandon Kaback
