So, in certain discussions the subject of railway gauge comes up and people talk about the pros and cons of particular gauges and their relative value versus other gauges. However, I don't know enough about railroads to understand why one gauge would be better or worse than another. The benefits of having a standard gauge are pretty obvious, but what would be the advantages and disadvantages of a wide gauge compared to a narrow one? Why would someone choose one over another for their railroad?
Thanks,
Jack
