NYC Subway Cars Costume

These are my two boys. They both love the NYC subway and wanted to be them for Halloween. I created these by looking at a Brio toy NYC subway. I basically constructed these out of cardboard, silver and black duct tape, and black sharpie. The front & back "doors" also have black plastic chains so that passengers cannot walk between cars. The markings are NYC subway appropriate (NYC Subway, Train Number, Letter of Line & Destination/Local)

The subways also have working headlights and taillights, and sound effects of a train announcement.
