Here is some scrap gons I"ve been working on !! ex BN now JETX 023, EX CP RAIL now ZVBX 10101 & BNSF 512043
They've seen some miles!!
I especially like the third one which seems very realistic to me.
You could even use mismatched trucks ...the repair shop got them back to work fast and looks didn't count . Nice work ! You can vary the scrap metal loads , almost for free , using wood shavings from a pencil sharpener ....if they are curled , all the better . I lightly spray them with grey , silver , rust ...what have you . Try it , you'll be surprised .

Those are some beat to heck gons!! Good work!
