What does the FRA require regarding torch cut bolt holes in rail for classes 2 through 5 track?

The FRA's regulations emphasize safety and structural integrity in rail systems, particularly for classes 2 through 5 track. The requirement that no rail shall have a torch cut bolt hole is rooted in the need to ensure that rail components maintain their strength and reliability. Torch cutting can compromise the integrity of the rail, introducing weaknesses that may result in failures or derailments.

Classes 2 through 5 track often carry lighter loads compared to higher classes, but they still must meet specific standards to ensure safe operation. Allowing torch cut bolt holes could lead to increased maintenance issues and safety hazards, prompting the FRA to prohibit their use altogether. This regulation underscores the importance of maintaining high standards in rail construction and maintenance to protect both rail workers and the general public.
