An 8 amp power pack shouldn’t damage any locos any more than a 5 amp power pack would damage one loco. The amount of current flowing from the power pack depends on the number of trains running.
If each engine draws 1/2 amp, then 10 engines would draw 5 amps. Thus a 5 amp power pack would be enough for 10 engines running at the same time. I’m not sure how much a typical N gauge engine draws.
Look for information in the papers with the loco on how much current they draw. Or, you might want to get an ammeter to see what it really is.
Don’t forget to include anything else connected to track power.
