A Picture Is Worth a Thousand Words

How things should be done. In this image, the Indian Pacific, Australia's premier transcontinental train, using engines and equipment very similar to American norms, passes a Transperth service. Because of Australia's ongoing gauge issues, Western Australia's rail network is dominantly the narrower Cape gauge, while the national network utilizes standard gauge. On either gauge, however, equipment and operating practices are similar to Chinese or American counterparts: those two Indian Pacific locos are essentially GE AC4400CWs in a different bodyshell.

In this image, heavy and light trains are operating safely alongside one another, on the same tracks. That FRA regulations prevent this--speaks volumes about the FRA.
