Pentrex Media Group, LLC, is an American producer and seller of railfan-related videos and DVDs.
Initially, Pentrex continued publication of books and all of the magazines it had acquired from Interurban Press, but these were gradually phased out, as the company concentrated on production and sales of videos and, later, DVDs.
Passenger Train Journal resumed publication in late 2006, with a new publisher, White River Productions.
[6] In 2007, the Midwest Book Review's "Wisconsin Bookwatch" recommended Pentrex as "the premier producer of railroading documentaries showcasing and highlight the trains and rail systems, the routes and histories, their engines, equipment, bridges, and more".
[7] On April 7, 2017, the company merged with Highball Productions and moved from Pasadena to Indianapolis, Indiana.
