In which classes is the use of a rail with a torch cut end as a temporary repair allowed?

The use of a rail with a torch cut end as a temporary repair is specifically allowed in emergency situations in class 2 track only. This is because class 2 tracks are often associated with speeds and operational conditions that may permit such temporary fixes, especially during urgent maintenance scenarios where a full repair cannot be immediately performed.

Using a torch cut end provides a quick, albeit temporary, solution to keep operations underway until a proper repair can be made. Regulations often specify that while certain emergency measures are permissible, they must be carefully controlled to ensure safety and compliance with railway standards.

In contrast, the other classes likely have more stringent requirements regarding track integrity and safety, hence the restriction on using torch cut rails in those situations. Such standards are designed to maintain a higher level of safety and reliability on tracks that may experience heavier traffic or higher speeds.
