It's free! Totally and utterly free.
It's an e-zine (I do so loathe these "e" prefixed phrases that signify intenet content myself but I have to move with the times) So it is a magazine that you download from the internet. With all the advantages that the internet and modern computer trickery can throw at you. Direct links to the advertisers website for example.
Have you ever looked at the pictures in a model railway magazine and thought.
"That looks neat I wish I could see it working". Now you can. For the "e-zine" has video in there too. A quick click and you can see a video of a train running on someone's layout. Want to see that working colour light signal work? Click and there you go it changes from Red to Green.
It is a great magazine, though it can be a bit strange at first when you compare the experience to that of looking through Model Railroader for example. I'm still not entirely used to it myself. But it is well worth a read and in these environmentally conscious days just think how many trees you're saving by having a magazine on your hard drive. Not to mention how easy the back issues are to store!
I like Model Railroad Hobbyist. I recommend that you take a look yourself.
