Installed the mod, but it causes the game to crash on startup.

Failed to load mod "TrainsReader 0.1.1"
TrainsReader/data.lua:2:
TrainsReader/prototypes/trainreader.lua:2:
attempt to call global 'deepcopy' (a nil value)

Thanks for testing.
It seems that libs, when globally loaded, apply to any mod. As I already used the function deepcopy in another mod, I had no crash.
This is fixed now (and tested with all other mods deactivated).
BTW, I removed a ghost item from the filters.
If any other crash, please let me know.
Many thanks
