DE10 Class 1667 - Model: DE10 1667 - Color: Blue/Gray - Wheel Color: Yellow - Coupler: With couplers I don't have batteries on hand, so I haven't been able to confirm its operation. There's a possibility it won't work even with batteries, so please refrain from purchasing if you are concerned. You can still play with it by moving it by hand even without batteries.
