"U" Style, split lighting board locomotive.

The “U” style frame is characterized by the long extensions of metal which rest directly under the decoder on both sides of the front of the decoder. These sections of the frame will prevent the decoder from being installed safely and properly.

To install a decoder in a "U" Style frame simply remove the section shown in yellow on the left from the FRONT SIDE ONLY, and make sure it looks like the image below. Once your locomotive looks like the one below you can pick up a CN Decoder and follow the "U" Style installation guide here
