I have a couple of Atlas GP9's and a 7 that are factory DCC equipped. They run great except they do have a bit of a time getting up a 2% grade with any more that about 4-5 cars. If I put a finger on them they move right along which tells me I might want to add a bit of weight to these. Problem is there really isn't much room.
Has anyone been successful adding weight to one of these?
Thanks
