Weights on n scale oil tanker

How do you put weights on n scale oil tanker with destroying it?

I'm not an N-scaler, but I have dealt with light HO tank cars.  If you can separate the top of the dome, put b-b's or sand into the tank.  If you can't get at the inside of the tank that way, you can drill a small hole in the bottom of the tank and use a little funnel to pour sand into the tank.  Cover the hole with clear tape. 

You might also want to post your question on the N-scale board.  Hope this helps
