Train Control Signals is a mod by Klonan with similar functionality. Can you offer any suggestions for when one might want to use this mod or that one?

Honestly, there isn't really a reason to use mine over that one, the other one looks a lot more robust in terms of functionality and usability. I made this mod because I couldn't find something better at the time, and I only uploaded it so that when my friends play with me they can get the mod without having to send them files all the time.

Gotcha. Fair enough, and thanks for the honest explanation!
