2010 2016 JMRI Suzie Tall suzie_tall@yahoo.co.uk 1.0 2016-12-02 ST Initial Version 2 2020-03-05 GM Initial version of the 1980 C&O Signal rules. This set was created by back dating the CSX-2014-Chessie rule set created by Suzi Tall. Back dating required removal of some aspects and altering the mapping to compensate for their removal. While based on the 1980 rule book, they are the same rules that were in affect in 1969.
