I don't really see this dynamic working in rail. In Japan, many of the companies operate trains on two gauges.
People read too much into this, it's mostly just historical reasons. Most slow Japanese rail has a quite narrow gauge which is less suitable for high speed trains. The interoperability benefit is limited since you typically won't want to operate both Shinkanzens and local trains on the same rail.
Having different gauges provides no real benefit. It's just that unifying gauges provides too little benefit to justify the massive investment required. I expect this to be the same for most other countries. (and for similar problems like different railway electrification systems within/across countries)

The only place it would be beneficial to have the same gauge would be at stations, to have fewer, more flexibile platforms and smaller train stations.
- The_Colonel 3y agoI can see other advantages like having same maintanence rail cars, emergency rail cars, ability to divert traffic in case of accidents. I guess there are even more such minor advantages.
- pvaldes 3y ago>Having different gauges provides no real benefit Unless you live in the Europe of Napoleon or Hitler, when they were built. Then the benefit is huge and obvious. Imagine how much easier the life would had been for Ukranians if the Russian trains that transport heavy army stuff would operate by default in a different rail width
