I am looking for advice/help regarding electronic uncouplers for stock with NEM couplings. I understand that Peco and Hornby offer electronic uncouplers. I have also read about Seep tension lock uncouplers. As I am new to the hobby - and making lots of mistakes! - I am trying to keep things fairly simple. Can they all be operated from a Hornby DCC Select controller? Are they ‘easy’ to install? Which look the most realistic? Thanks.
