Howdy, thank you so much! glad you are enjoying them so much! as far as the signals, I know have different signals for different speeds. the Yard Speed signals, you have to be much closer before they activate. the normal ones are for mainline speed and activate further out.
As far as FS25, yes I have every intention of bringing them to FS25 at some point! I dont currently own FS25 yet, but at some point I will convert everything to FS25
