The decoder was then updated with the latest R class project, and following successful testing, the tender was reassembled.

This model came with the original QSi Solutions decoder from 2013, which was no longer working. A LokSound V5 decoder was hardwired to the model, and a single 4 ohm large hi-bass speaker was fitted. A custom enclosure was produced to suit the available space and hi-bass driver. This speaker is available through the DCCSound website.
