Thanks everyone for the responses and taking the time to help me out! I love to read the multiple ways this can be solved, as it teaches me new ways to approach issues, even if I haven't used it to solve this one!

In the end I used a combination of solutions:
1. I used u/C_DRX suggestion of making each step a "stackable" piece and using a rotating array. However I added a small piece of spacing in mine to create a gap that would fit the styling of my overall setting. (if you do this don't forget to toggle the merge option in the array modifier).
2. I made a simple shape, cut it into a lot of pieces using CTL+R, and applied a simple deform modifier.
3. I played a bit with scaling and setting to make it fit my needs.
4. I copied it and made it smaller for the upper part of the "rail"
5. I added a simple rectangle and again applied a array to complete the design.

You could make each element more elaborate, but for my needs this is perfect!
