There were a number of large {{Track gauge|3ft}} railroad systems in North America; notable examples include the [[Denver & Rio Grande]] and [[Rio Grande Southern Railroad|Rio Grande Southern]] in Colorado; the [[Texas and St. Louis Railway]] in Texas, Arkansas and Missouri; and, the [[South Pacific Coast Railroad|South Pacific Coast]], [[White Pass and Yukon Route]] and [[West Side Lumber Company railway|West Side Lumber Co]] of California. {{Track gauge|3ft|disp=1}} was also a common track gauge in South America, Ireland and on the [[Isle of Man]]. {{Track gauge|900mm|disp=1}} was a common gauge in Europe. Swedish three-foot-gauge railways ({{Track gauge|891mm|disp=or}}) are unique to that country and were once common all over the country. Today the only 891&nbsp;mm line that remains apart from heritage railways is [[Roslagsbanan]], a commuter line that connects Stockholm to its northeastern suburbs.
