|I ordered one of these from ETH a couple months ago. It arrived in good order and I've had a chance to test run it. My findings:
Very nice runner, and out of the box it is a pretty good speed match with old Berliner 0-8-0 tank engines (Class BR81 and BR92) so runs well in doubleheader with those. The old Berliner 0-8-0's do not have working lights so this is a nice feature of the Roco model as well.
Mine came with Tillig knife couplers installed and ready to go with my Tillig and Berliner rolling stock, but possibly George changed these out for me before shipping from ETH - if so, thanks, George. Either way, apparently Roco TT locos can be easily fitted with Tillig NEM couplers, which Roco product descriptions are a little unclear about.
High marks all around on this excellent model.
