On level 7 you will come across a train guarded by the Nazi's, after killing the Nazi's capture the train, using this train you have captured look to your left while in the train and you will see another train just like this train. Destroy that train and the achievement is yours.
If your train is taking alot of damage, you can always jump out and repair your train by looking at it and hitting the A button.
When going through this game which I am highly recommending doing is using the Xbox Achievements road map made by CienPR, when you hit each level of the story just hit CTRL+F on the page and type the Mission you are on, and you will find the achievements you need to look out for and how to do them on each mission. There is about 2 each mission, and there aren't any videos which I would be posting if I could find some, but I guess this game isn't popular enough.
Again credit goes to CienPR, good luck and have fun
