e/Modelling 3' gauge railroads

Information
has gloss	eng: Modelling 3' gauge railroads is part of the hobby of rail transport modelling. Specifically it relates to the modelling of narrow gauge prototypes of gauge. This gauge was the most common narrow gauge in the United States and in Ireland. Apart from some other lines in North, Central and South America, gauge was uncommon elsewhere. Therefore most gauge modellers model either United States or Irish prototypes.
