This item came with the 60052 Cargo Train set I bought for my boys. When I put new batteries in, it would not work at all. I looked closer and see the metal contacts for the battery top posts are recessed too far and the batteries cannot make contact. I put a small piece of aluminum foil in the recessed hole before putting in each battery and it works perfectly fine. I am using Duracell batteries so it isn't a low quality battery problem. Perhaps I just got one from a bad batch? Or have others experienced this same problem?

Too fast for train unless you have the receiver
Why not add a few speeds for this? Without the receiver which is back ordered until after Christmas, the remote is useless. The train goes so fast it runs off the track and falls apart. Misleading/Poor planning lego. The description should explain that it cannot be purchased alone unless you are replacing a battery and you have the rest of the components. Honestly it should be sold as a set battery, receiver and remote.

Great accessory basic machines+Long battery life
I first got this Bat box in the (7939) Lego city cargo train. It powered the train motor very well. It managed (with struggle) to go up a very steep slope in the train track, while pulling all three trucks. I bought some Lego Power functions lights (8870) and put them at the front of the train. The Bat box powered the lights and the Train with all three trucks up the same slope. However, when I ran the lights while the train motor was running at full speed (7/7), the lights would only run at 6/7 brightness. I also bought a second one of these Bat boxes, two M motors and an Ir receiver and I put them in my train crossing (7936). I put that receiver on freq. 3, and the train receiver on freq. 2. With that done I could control the train speed and lights, then put the boom gates down, and run the train over the Train crossing.
Now for the pros and cons:
-Very long battery life (only went through 2 loads of 6 AAA batteries in 3 years.
-Easy to assemble and connect motors
-Very bulky, takes up a lot of space.
-Heavy (some motors aren't strong enough to pull it)
Summary: Very good motor, definitely recommend it to any Lego fan.
