If locomotives were imported from elsewhere, especially in the early days, the track would be built to fit them. In some cases standard gauge was adopted, but many countries or companies chose a different gauge as their national gauge, either by governmental policy, or as a matter of individual choice.<ref>''[https://digital.lib.washington.edu/researchworks/bitstream/handle/1773/21998/Starns_washington_0250O_10676.pdf The Russian Railways and Imperial Intersections in the Russian Empire]'', Karl E.
