Solving the problem of switching from one track gauge to another in the context of the requirements of interoperability specifications for classical infrastructure

The article discusses issues related to solving the problem of switching from one gauge to another. A progressive solution to the problem of different track gauges is the use of a combined gauge design. The combined track solves the problems of overloading, downtime, and wheel set problems. The design of the combined gauge has set new challenges for track infrastructure workers and scientists. The first task is the strength of the combined track structure. The second task is the stability of the combined track plates. The third task is to lay switches in the combined track and determine the permissible train speeds.
