passenger trains

i have my new kato n scale corregated passenger cars. now what is the CORRECT order for the cars?

Do you mean what order do they appear in a train?? If so, that would depend entirely on the train you are modeling. As a VERY broad rule, however, a passenger train from from front to rear would be: express, mail, baggage, coaches, diner, lounge, pullmans, observation (if any).
