The CN-GP follows in the same style as the Classic N decoder. This decoder features a split decoder, designed to fit in split lighting board GP Locomotives. As with the CN a small amount of soldering is required, but it is still far easier than milling the frame and adding LED's. The CN-GP comes with onboard sunny white, super-bright, forward and reverse LEDs.

The CN-GP features the TCS exclusive auto-adjusting BEMF for incredible slow speed control.
