1/35th Scale Model Railroading

In some ways, 1/35 models are becoming out of date. 1/48 is very popular and selection is growing.

There isn't a working model railroad scale at 1/35 that has subjects that match what's available in plastic armor modeling. 

There are a number of gauges of model railroading, so they don't really need another.  1:35 would be between O gauge (1:48) and G gauge (1:22.5).  The size of a railroad at 1:35 would be pretty large.  G gauge is sometimes called Garden railroads because at that size an outdoor layout in a back yard is about the only option.  Even O gauge takes a major portion of most basements and the large size and limited popularity make it expensive.  HO (1:87) and N (1:160) are the most popular because the smaller size allows a big layout without taking over the whole basement.  Since G gauge and O gauge have existed for quite awhile, and folks have invested much in their layouts, I doubt if another large gauge would have much interest.

There's an incidental benefit to having a static model railroad. It's much simpler to model details of the track, roadbed and equipment like signals and switch stands at scale.
