Model Railroader 75th Anniversary DVD

As is the case with many model railroaders I received a copy of Model Railroader's 75th Anniversary DVD for Christmas.  I'm sure you've heard of it, but in case you haven't it's all 912 issues of Model Railroader magazine from 1934 to 2009 on a 3 DVD set.

It has a lot of great stuff in it but it also provides an interesting window into the history of model railroading as a hobby.  Using the "full text" search options here are some interesting bits I pulled out.

First mention of...

• On3 - June 1936
• HOn3 - November 1948
• Sn3 - May 1950
• Sn2 - January 1954
• HOn30 - April 1972
• On30 - November 1974
• Gn15 - Not able to find the first, but I did find what is described as a '1/2" scale 18" gauge 0-4-0' which looks mightily like Gn15 in the October 1986 issue.
• PWM (pulse width modulation) - December 1976
• DCC - February 1989
• a website - July 1995 (atlasrr.com)
