Märklin 74462 Einbau-mfx-Digitaldecoder/C-Gleis Weiche Model Railway Accessories, Multi-Coloured, One Size

Expensive kit from maerklin! To use the Märklin H0 20997 Electric Decoupling Track I needed to do some soldering to use it for the digital track. Works well . The digital switches are minute and difficult to set but solid and work just fine.
