No. Maybe if I worked with HO stuff. The details they "add", are they the same detail parts that come with Kato HO locomotives in the box? Or are they additional details that you can buy off Kato or some other manufacturer? The only thing they do for N Scale locos is sell them with Decoders. But I can install a decoder myself and make it a lot cheaper. I wish the N Scale locos had the same detail parts than their larger HO cousins.
