Atlas RS1

Now that the Atlas Light board version of the Tsunami is available, we are proud to show the installation of that fine decoder into an Atlas RS-1. This is the first procudtion install in a customer's loco - it has been waiting about 4 years for this install.

In 2009, SoundTraxx released the 828049 version of the TSU-1000 decoder which was recorded on a real, live RS1, making this a SPECTACULAR installation with that decoder!


BASIC INSTALL: The Tsunami was snapped in place of the removed Atlas Light Board with the Forward direction on the decoder matching the F on the loco (long hood in this case). A small styrene mounting sheet was installed between the bosses on the weight over the front drive train. It was bent slightly to increase clearance against the hood. The capacitor was affixed to this plate with foam tape. The motor and rail power were wired to the decoder. The loco was tested for proper directional operation.

LIGHTING: To make room for the install, we removed the light pipes from the shell and mounted Sunny White LEDs in place of the light pipes. A resistor was installed in one lead of each LED and the LED and resistor pigtailed with color coded wire (blue to Anode - long LED lead - through resistor; white or yellow to the other LED lead). Shrink tubing was used ot insulate the connections. The LED was held in a set of clamping tweezers in a vice pointing up. Faller Expert Styrene cement was applied to the shell and the shell positioned over the LED with gravity holding alignment. When one LED was dry, the other was cemented. This removes the light supply to the number boards, which was pretty weak to start with. additional surface mount LEDs could be used on the number boards, but the compexity exceeds the result in our opinion.

SPEAKER: A pair of violet wires were attached to a 16 x 35 mm speaker. It was mounted in the shell below the LED on the short hood. An enclosure was made by putting 0.02 inch thich styrene between the speaker and the sides of the shell. The wires for the LED and speaker were routed along the top of the hood toward the middle of the loco. The open end (near the cab) was covered with 0.04 inch thick styrene - or use two pieces of 0.02 thick!

FINISH: The LEDs were wired to the connections on the ends of the boards, observing correct polarity. The speaker was wired to its terminals. The Lubrication was applied as needed. The decoder was programmed and the shell snapped back in place.
