Hi ShaggyHare67 ,
Yes the trains.conf created by trains-agent is basically an extension of the trains usage (specifically it adds a section for the agent)
I'm assuming you are running the agent on the same development machine.
I guess the easiest is to rename the trains.conf to trains.conf.old and run trains-agent init
(No need to worry, the trains package supports it , so the new configuration file that will be generated will work just fine)
