I have 3 variations on these RS-1 switchers from Atlas, all in Santa Fe zebra stripe paint scheme. One has full sound and DCC installed from the factory (5876-3 from 2010); one has 2-rail TMCC installed (5876-2 from sometime in the early 2000s); and one (7876-1 from 2002) is just straight DC. This is the straight DC version that I am upgrading.
Even though this version is straight DC, it did come with directional lights and smoke and speaker (because it was billed as "DCC ready"), and I wanted to keep it all. Was just a matter of tearing out the DC board and connecting everything (plus a couple resistors) to the ESU LokSound.
Here is where the headlights connect to the board.
Here is track power coming into the board and motor control leaving the board.
Got some basic connections soldered to the LokSound board (track power in, motor control out, common and headlight control). Excuse my horrible soldering, still a work in progress!
Removed speakers to solder connections. (yes that is Atlas switch wiring that I am using!)
More awesome soldering.
Hard to see, but I got the smoke unit connected to common and AUX3.
Tidied things up a bit with a small piece of foam board and a couple miniature zip ties.
Put everything back together and we are in business!
Thanks for watching.
