Toy Train Gauges
Gauges related to toy train sizes were first introduced by German toymaker Märklin way back in the 1890s. It’s true that Märklin pioneered many aspects of toy trains, but other manufacturers soon followed their lead, adopting and adapting gauges for their own products. In fact, some variations still exist within gauge standards around the world because of manufacturer differences. This page gives a bit of information about the most popular gauges seen on toy trains in the USA.
