The Mikado received its LokSound Micro decoder and speaker in the tender.  We completely rewire the loco to avoid intermittent contact on the tender draw bar.  The yellow Kato LED is replaced with a white LED.

We add 4 red LEDS and 2 white nano lamps to create the effects.  We also created the light pipes for the red lamps and flashing ditch lights on each end of the loco.



Kato N Scale PA Diesel in Southern Pacific Daylight paint with Sound and Light Package.

We custom mill the frame to accept the LokSound Micro decoder and speakers.  Custom wire the simulated MARS light and modify the light pipes to separate the headlights.  We also upload a custom sound project to the decoder.


Kato N Scale GG1 loco with Custom Sound package.


This is a challenging loco to add sound.  We mill the frame to accept the LokSound Micro decoder and speakers.  Wiring requires modification of the light board.  The work is well worth the outcome!



Con-Cor N Scale AreoTrain w ith custom sound installation and loco cab and number boards wiring.

This installation utilizes the Con-Cor N Scale sound car for the decoder and speaker installation. We, of course, go one step further and wire the number board and cab lights to the decoder so that you have complete function button control of your loco lighting. Very nice effect!



Kato E8 with Custom Sound package

To install the LokSound micro in this loco we mill the frame to add the sound decoder.  We also modify the factory light board to provide space in the loco and to give electrical pickup to the decoder.  The decoder is loaded with a TophobbyTrains custom sound project.


This install uses the LokSound Micro for sound light and motor control.  The frame is milled to accept 2 LokSound speakers.  the light board is modified providing light pickup and space for the decoder. 



Kato N Scale GS4 Southern Pacific with Tsunami Micro Sound decoder and custom Mars light wiring.

We do a complete rewire on the GS4.  From the time we found the short in the quad frame and reported it to Kato we decided to eliminate the shorting problem making a bullet proof solution. 

This mod uses the Soundtraxx Tsunami Micro Heavy Steam sound decoder.  We completely dissemble the loco and tender rewire the motor control circuit, modify the MARS light for DCC simulated MARS operation.  The decoder and speaker are located in the modified tender.  The results are outstanding.  We custom program the loco to take advantage of the vast operating characteristics of the Tsunami.
