You asked specifically about Internet sources. I will generalize that to all sources. I get about three fourths of my info on toy trains from the internet.
25% -non -internet sources. Trainshows, friends, stops by any of the three LHS I go to.
25% - OGR Forum - I come here mainly because it is interesting and fun, but it is the source of perhaps another 25% of the information I hear about toy trains, etc.
20% - manufacturer's catalogs catalogs and websites - especially their catalogs on their websites: Lionel, MTH, Bachmann, Atlas, RMT, woodland Scenics and Menards. I routinely check all and study them. You learn alot that way.
20% - the websites of internet retailers: I go to and study them. . . I routinely check about six to eight each week, includingMicromart, Modelexpo, Patricks, Nassauhobby, modeltrainstuff, Walters, Amazon, Diecast direct, and some others. M. B. Klein (modeltrainstuff.com) and Diecastdirect have the best search engines and product filters and I depend on them more than the others.
10% - e-mail. A lot of good information comes in via e-mail from manufacturers (e.g., Menard's and RMT newsletters, etc.). I carry on e-mail correspondence and discussion with a number of other model train enthusiasts, as many people here on the forum, as
well as two shop owners and one or two people who work at manufacturers, and two other model train book authors, .
