I've just received my 30069 its a beautiful model and has plenty of weight in it, so it should be good at shunting some of the longer heavier trains on my layout. I've attached some images (from my phone so not great quality) a bit of a shame about the over exuberant lubrication that has leaked a little but it is normal from Bachmann... I just need to chip it. Has anybody fitted a chip in one of the BR ones? is it relatively Simple?
