what would you say are the main difference between this mod and https://mods.factorio.com/mod/transparent-elevated-rails, as well as the up & downsides of either?

This mod was heavily inspired by transparent-elevated-rails with some improvements that is thanks to the way I've wrangled the engine to replace the rails:

Pros

Configurable transparency: Adjust transparency levels (0-100%) for rails and supports separately
Global toggle: One button affects ALL rails on the map instantly, no manual clicking required.
Train bug fix: Automatically handles occupied rails - retries when trains leave instead of causing errors

Con?

All-or-nothing approach can't selectively toggle individual rails like the original mod

Thanks, others didn't work well for me
