LEGO remote control 8879 for 2016 Winter Train not working I purchased parts 8879+8884+88000+88002 to power the new Winter Holiday Train.  Fresh out of the package the remote controller 8879 does not make contact with the positive end of the battery. 

Thanks to this post, I was able to make an adjustment to the controller so that contact could be made saving me a lot of time and headache. Is there an easy way to get the positive contacts to stick out further?
I had the same problem, so I looked at the forums, but I couldn't solve it.

In fact it is a problem with the contact, so I put some aluminium foil (the same one from the kitchen) in the positive contacts, and it worked!!! Yeah, I used DuraCell...
