This is an Atlas ALCO S-4 switcher which I recently bought. It was a rough runner with regular bulbs and running on DC. This is my first proper conversion from scratch using Loksound v5, sugarcube speaker and LED lighting on the front and back. I used a resistor board to turn down the power of the LED's but they're still pretty hefty. I could do a better job on hiding the wiring, but I'll keep that job for another day. I've fully serviced the loco and it runs sweet as a nut.
