One of the things I enjoy the most about O scale (and model railroading in general) is the technical challenge. I am not always about practicality, and there is certainly nothing practical or sensible about adding DCC to a reasonably stable DCS layout. However, the itch of the challenge will always win, and it would seem a lot of fun to take on the challenge of installing LokSound in a few motors and see how it all works as compared to DCS. The primary motivation (beyond said challenge) is the awesome sound files that are available for Euro motors, of which I have two, plus an Atlas AEM7.
I used to use DCC in my HO days, and it drove me batty. I didn't get along that well with HO in any case, but the frustration with DCC was the 'last straw' before I went with 3R scale for good. However, ESU's system appears quite friendly and highly thought of, and their sound files are fantastic. The more I read up on it, the more I want to try it! I registered as a member of the ESU forum, which is closed; an ESU employee has to clear your registration, (or so the website says). I have also reached out to the US distributor of ESU products in Montoursville, PA, which is only a few hours away from me.
Assuming my contact with them is satisfactory, I think I am going to get a design together and undertake a slow but steady addition of ESU Loksound to the 300 Loft RR. It just so happens that I have an 'open space' on my homebrew control surface for another control system, such that I can switch what feeds the catenary on the fly. I had worked this feature in when I designed the board with the idea of adding a conventional transformer to the mix for visiting trains. Sadly, I have yet to host a single visitor who models 3R scale, much less bring equipment to run. As such, I think I will ditch the conventional idea, and insert LokSound in its place. That way, the back end is already set, I just need to add the system itself to the front end. DC+ to the overhead wire, DC- to the outer two rails, and a separate programming track.
Perhaps I should start a GoFundMe and see if anyone wants to subsidize my control additions.
