Dave and All,
    Perhaps the railroad notion is a blind lead.  Not too infrequently rules
are found with the NYC mark in one form or another.  It has been suggested
before that this referred to "approval" for bulk purchase by New York City
authorities for use in schools or other city departments.  Ditto for the
Commonwealth of Pennsylvana.
