Upgrade the E 50 (39500) with a LokSound decoder: 

I think that the nice E 50 with Soft Drive motor needed a LokSound decoder. I removed the sound pcb board and speaker. I unsoldered  the 4 wires carefully as seen in picture #2. Then I programmed a ESU LokSound Mfx #62499 decoder with the sound project #62466 and mounted a new speaker #100622 as the speaker that was included with the LokSound decoder was to big. In picture #3 the new LokSound decoder and speaker are in place. Now the model just needs it body back. Nice conversion.

This model was the next on my list and you can see in picture #1 the original decoder and light pcb. I removed all of it as seen in picture #2. In picture #3 the speaker #100622 and the 21 pol mtc #113556 is in place with the ESU LokSound Mfx #62499 which I reprogrammed with the program #63446.

Converting the E44 (37440) to Mfx with sound:

The E44 is a really nice model ! Here it was no room for a 21 pol pcb. Picture #1 shows the model as original with that very special decoder and sound modul all in one ! Anyway I removed it and mounted a new speaker #100622 as shown in picture #2. Then I soldered in a ESU LokSound Mfx #62400 decoder which I reprogrammed with program #62470.

I removed the old decoder. I used a 21 pol pcb #119605 and the Mfx decoder #118436 from model #37151. The pcb itself is hold in place by a plastic clip holder #405040. After carefully removing some plastic with my Dremel I put the speaker, #100622, in the tender top as you can see in picture #3. The sound is really nice, actually better than in the model #37151...

I removed the old decoder as you can see in the first picture. I used a 21 pol pcb #113556 and a ESU Loksound Mfx decoder #62499 that I reprogrammed with sound program #62432. The pcb itself is hold in place by a plastic clip holder #405040. I had to put the speaker, #100622, in the plastic body just behind the motor. Now this lowely little loco is one of my favourites...

Converting the Br. 52 from the set 26830 to Mfx with sound :

Converting the V 100 (37724) to Mfx with sound :

Converting the Br. 96 (37963) to Mfx with sound :

This is a very special model, very beautiful ! I removed the old decoder and other parts. The speaker is mounted under the black plastic holder #106042. I used a little bit glue just to be safe. The holder is clicked in place. The 21 pol pcb # 611626 also clicks in place, very easy mounting. Then I just plugged in the Mfx decoder #611627 as well. A really nice model has been even better...

Converting the Br. 52 K (37171) to Mfx with sound :

With this big locomotive I used parts from the model 37022, new tender bottom #203706, 21 pol pcb #610984, decoder #611012, Speaker #508609 and holder for the speaker #209693. First I had to remove the old parts, decoder and tender bottom as you can see on picture #1. Then install the new parts, see picture #2. A lot of wires... The first testing, seen in picture #3, was really nice, what a sound ! Then I needed to test the fan motor as you see in picture #4 and #5 where it is finally installed in the tender top. Nice conversion !

Converting the E 19 (39190) to Mfx with sound :

The E 19. From factory it had a C-Sinus motor and dekoder which I sold on eBay. I got a new motor boogie #307130 and mounted a 5-pol motor instead. This way I could use a 21 pol pcb #113556 and a ESU Loksound Mfx dekoder #62499 which I reprogrammed with the program #62492. See picture #1 and #2. As there is very little space inside this locomotive I had to use a very small speaker. I had a speaker #113566 (Sound chamber #103610 and #103611 is also needed) that I put inside the higher roof as you can see in picture #3.

Converting thr Br. 59 (37058) to Mfx with sound :

This is a very nice steamer ! I used a 21 pol pcb #611262, dekoder #611261 and speaker #100622, a new tender bottom to #120786.  A rather big and expensive conversion but worth it, recomended !

Upgrade the Crocodile from the set 29680 with a LokSound decoder :

This is my first conversion of a model with a Soft Drive motor ! Picture #1 is the Croc as it is original but without the top. The decoder in picture #2 I took out as also the speaker and sound pcb in picture #3. The 21-pol pcb in picture #4 I reused for the LokSound decoder, a ESU LokSound Mfx #62499 that I reprogrammed with program #62471, as can be seen in picture #6. Picture #5 shows the new speaker in place, a ESU #50447.

Upgrade the model 39540 Gottardo with a LokSound decoder:

Parts needed :

ESU #62499 LokSound mfx decoder.

Speaker : ESU #50441 or Märklin #100622

This is a very nice trainset. Took out the old speaker and sound pcb. The old decoder I replaced with a ESU LokSound Mfx #62499 decoder which I reprogrammed with the sound project #62497. I used a ESU #50441 speaker and mounted it in its special place. Now it's even nicer !

Converting the Ce 6/8 from the set 26730 to Mfx with sound :

Parts needed :

21 Pol MTC = #113556

Loudspeaker = ESU #50442

Plastic holder for MTC = #405040

This model had a 6090 decoder and DCM motor installed from factory. I removed the decoder and placed a plastic holder #405040 in the same place. Then I put in the MTC #113556 and soldered the wires. A lot of them as seen in picture #1. Then I put in the ESU LokSound Mfx #62499 decoder and mounted the included loudspeaker, ESU #50442, as seen in picture #2. Putting on the left hood, seen in picture #3, be carefull with the wires ! Then I put the locomotive on the programming track, as seen in picture #5, and reprogrammed the decoder with the sound project #62471.

Converting the ET 87 (37265) to Mfx :

First I did want to convert this model to Mfx with sound so I ordered the 21-pol pcb #105307 from the model #37266. When I did opened my model I couldn't find any place for a speaker so I then desided to use a ESU LokPilot Mfx decoder. First I removed the top of the middle part of the train as seen in picture #1. Then I wrote down where all the different wires went from the old decoder as seen in picture #2 to know where to put them on the new pcb. Rather easy as the wires are in the same place on the new pcb. Picture #3 shows the new pcb and decoder in place ! Now I programmed the decoder with the project file from the model #37266 which I got from a friend.

Converting the Br. 80 (33041) to Mfx:

The Br.80 is a nice little steamer ! I took out the Delta decoder and upgraded the motor, see picture #1. I got a 21 pol mtc pcb from X-Train as seen in picture #2. You can find details about this pcb here : http://pcb.x-train.de/ (In German only) In picture #3 the pcb and decoder is installed and ready for programming...

Converting the E 18 from the set 26509 to Mfx with sound:

This locomotive is very nice. The loco before conversion in picture #1. I stripped it down except the motor as seen in picture #2. Then I installed the speaker #113566, the box #103610 and #103611 is also needed and the 21 pol pcb #113556 as seen on picture #3. After this I mounted a ESU LokSound Mfx #62499 decoder which I reprogrammed with the program #62492. Really nice !

Converting the Br. 24 (36240/36241) to Mfx with sound modul:

The new Br.24 is a nice model. I removed the old decoder and installed a 21 pol pcb ESU #51968 this time as it has amplified outputs for AUX 3 and AUX 4 on the pcb. See picture #1. I used AUX 1 for the smoke generator. In picture #2 I have put in a soundmodul that I had left over from one of my other conversion's. The speaker is glued in place. Picture #3 it is finished and ready for programming and testing. Now I have both my Br.24 with smoke and 3 different sound's !

Parts used :

ESU LokPilot Mfx decoder #61600 or #61601

21 pol MTC pcb #111335 or ESU #51968

Plastic holder #405040 for the 21 pol MTC pcb.

Upgrade the Re 4/4 I (39420) with a LokSound decoder:

This is a very nice model as seen in picture #1. In picture #2 the shell is removed. I removed the decoder, sound modul and speaker. Then I made a small veroboard for the resistor for the speaker. A new speaker #100622 is installed. Then I took the ESU LokSound Mfx #62499 decoder and reprogrammed it with the sound project #63447. A really nice conversion !

Converting some model's to Mfx....

The last days I have converted the model's 30000, 34133, 36740, 37132, 37250, 37365 and 37562 with a Mfx decoder,,,

Converting the Ae 3/6 (37512-02) to Mfx with sound:
