Just like the picture show.

I found that I had to overwrite the JSON file to translate train's name.

That's going to be tricky, but I'll see if I can provide a way to do that

thanks

You can now override the json names with immersiverailroading:entity.type.name=override
Ex:

immersiverailroading:entity.locomotives.emd_sd40-2=Super Magic Train
