The Mehano Vossloh G2000 looks good. Period. Did I mention it was black?
In a recent article, I mentionned why I thought the Next18 interface was the best choice for future N scale model. I have converted many models to DCC, sometimes soldering decoders in the locomotives, sometimes using the outdated NEM651 interface. But because the NEM651 interface is outdated, I always ended up still soldering some wires to the locomotive. For example, the plus pole (useful for lights to avoid flickering in DCC) is not part of the NEM651 interface. So in the end, I always ended up defeating the purpose of a digital interface (enable easy decoder changes).
So for this Mehano Vossloh G2000 locomotive, I decided to do my very first “Next18” conversion. This means I removed the original NEM651 board, and added a Next18 interface for Next18 decoders.
The interface allowed me to “pimp” the locomotive, without soldering a single wire to the decoder:
For this conversion, I used the following:
I totally removed the original board, and replaced it (partially) with a custom board. It holds a switch to temporarily disconnect the capacitors (sometimes necessary for decoder firmware updates), a resistor and a diode (allowing a safe charge/discharge of the capacitors).
As per all recent conversions, I won’t detail all the steps, but feel free to ask questions in the comments!
Original board of the Vossloh G2000
Original NEM651 board removed
Doehler & Haass Next18 adapter fitting perfectly
Original NEM651 board
Custom board with switch, resistor, diode
Custom board in place
Board and capacitors
All elements in place
Final result with DH18A Next18 decoder
Doehler & Haass – DH18A Next18 decoder
Next18 adapter in place and soldered
The Mehano Vossloh G2000 works perfectly (even better now, with the capacitors), and I will be able to change the decoder easily in the future without compromising any function.
This is probably the first of a long series of Next18 interface conversion!
