Hi,I'm new to forum. Just purchased a Lionel 2026. Put track together and ran for about 5min. came back later train started and the stopped running. transformer is good. I found different post about the E unit and brushes may need cleaning. The one post I found about removing shell didn't give enough info how to get completely off. I removed some screws and the rod in the back but something is still holding on. Maybe some pics or a good step by step would greatly be appreciated.
Thanks
