Here are some external web resources that we find informative on European rail history and model trains.
Miniatur Wunderland
For many, Miniatur Wunderland will need no introduction. It is the world’s largest model railroad, located in Hamburg, Germany. While the scale and scope of Miniatur Wunderland is beyond most modelers, they also publicize many of their innovations in the field of model railroading, helping to lower the barrier of entry to all modelers. https://www.youtube.com/@MiniaturWunderlandOfficial
Märklin Of Sweden
Martin of Marklinofsweden is another popular and well-regarded Märklin content creator. Most of his videos are tips and tricks for making a Märklin model layout; he features integration of a plethora of emerging technologies, especially 3D-printing. His emphasis is “model scenery creation… to push the limits for increased realism and still keeping the methods and materials simple and low cost.”
Osterthun
Beautiful pictures of many models produced from Era I, II and III. Navigation takes bit to get used to, and there are multiple ways to find the models. Click on the picture if you are unsure. If you know the Era, organization and BR designation, go to Model Trains, then click on the picture to start you search. Once you have found your model, the left list are all organizations that have that model, from Era I, II and III. Default is Era II and DRG, and click the organization you are looking for.
The 3rd Rail
The 3rd Rail is an excellent resource for Märklin enthusiasts, especially those interested in the 1980s. His videos are often a blend of real-train history, Märklin history, and a demonstration of various facets of the Märklin ecosystem.
Jago Hazzard
Mr. Hazzard produces well-researched videos on rail transport in London. Expect regular use of dry tongue-in-cheek humor characteristic of England. The majority of the videos pertain to the London Underground and its precursors.
Eisenbahnstiftung
Huge picture archive of European prototype pictures. This is a very useful picture archive when you want to figure out how exactly a certain train looked like. Search by free text or by BR#.
Modellbau-Wiki
Wiki database for European model trains. Search on any model, or use the navigation page. Lists all models produced of a certain prototype. Fairly complete, but have several missing models, especially older models. As a wiki, you can add or edit information in the database.
Stummiforum
The largest discussion forum for European model trains. Mostly in German, but Google Translate works pretty well if you need some help with your German.
Marklin-users.net
Largest international discussion forum for all things Marklin. Mostly in English. Need to register to post, but anyone can read.
