After many many readings I think I'm ready to jump into the digital world. I have a small layout (8 ft x 8 ft) and want to run no more than three trains at once.

I plan to convert my 3048 to digital first and gain some experience before working on the others. Here is a list of what I think I need:

60653 MS2
60113 Connector Box
66365 Power Pack for 60113
60944 Motor conversion for 3048
60945 Sound Decoder

Do I miss anything or pick the wrong equipment?

I read the descriptions for Sound Decoder 60945 and 60965. But it is not clear which one I should use.

Any suggestion will be much appreciated.

Thank you.

IMHO the 6094x decoders are the better choice for analogue locos with the mechanical reverse unit.
The 6096x series might be better for locos with limited space (no MRU) or 8-pin decoder socket.

For flicker-free headlights you might want to go for new bulb holders (and new light bulbs) or for LEDs.

Hi,

Beware ! The 3048 has a non standard brush-plate, the 60944 kit won't fit.

I've converted mine with a permanent magnet from ESU adapted for LFCM motors: 51960, and kept the original 3 pole motor and brush-plate.

The 3048 is not listed in the booklet :

When the motor is converted, you may use a decoder of your choice (see Tom's advice)

Cheers
Fabrice

I agree with Fabrice,

I have recently bought a Primex 3193 which is the same (I believe) as the 3048. I have on order a Lokpilot set with Hamo magnet for its conversion.

Märklin Magazin wrote that MLD and MSD are not suitable for three-pole motors with HAMO magnets.
So if you buy an ESU magnet, better get an ESU decoder to go with it.

Hello,

The conversion using the 60944 and 60945 can work nicely in the 3048.
As mentioned, the 60944 plate does not fit perfectly but a simple cut of the one corner will allow it to fit snugly enough, so it is actually ok.

Hi .. hit the send button too quickly ..

Wanted to add .. this conversion which you are contemplating is fairly complex in the digital conversion space.

An easier conversion to start with would be using a more modern locomotive which has enough room inside the main body to fit a decoder, and try a straight forward 60760 decoder (decoder + motor). Consider maybe an electric loco or a diesel loco which has a Delta motor if you have, to start off.

Hi Fabrice,

The url doesn't work. Confused

After reading all the comments and suggestions, I'm leaning toward converting my 3082 instead of the 3048. I also like the sound of the steam engine so I'm skipping the 60760 motor + decoder combo and go with the 60941 and 60945 mSD.

I'm not sure if all that would fit into the coal car since there isn't much room in the main body and it is where the mechanical reverse switch resides.

Have anybody done this on the 3082?

Thank you.

I did a 3048 digital conversion:

UserPostedImage

I don't have any other pictures but can take some if you wish.

I found a kit on ebay.de for the 3048 which included the motor plate, a 5-pole armature, permanent magnet, chokes and screws. I believe the kit number was 60904 but had a special motor plate for the 3048 and it was out of production. I think I got lucky finding this old kit.

With an ESU 51968 21MTC adapter I located a hole in the PCB in just the right place so as not to short out any of the traces on the PCB and attached it to the existing post used for the reversing relay.

Using some prototyping PCB, I fabricated a PCB for the headlight using a solder type bulb socket. To mount the assembly, I had to drill/tap a hole for the screw. Another piece of prototyping PCB was used to attach common grounds, headlight power and a 2-conductor plug for the smoke generator (black wires with white trace). The positive of the smoke generator was attached to AUX 3 of the 21MTC adapter. You cannot use chassis ground for the smoke generator so you will need to get a Seuthe 12 (it came with a fiber smoke stack) with wire leads and connect a 2-conductor lead with socket to mate to the 2-conductor lead plug from the 21MTC. I found these small plug/socket wiring at the local hobby store.

I mounted the speaker in the tender. Had to cut some of the plastic away to make room for the speaker and wiring which is a 4-conductor plug/socket assembly. I used a 4-conductor cable thinking I may want to add reversing lights to the tender.

All the wiring is PTFE 28ga from these guys Bulk Wire and you can get the colors to match the Marklin color scheme.

It works great and sounds great.

The only issue is the smoke generator. Removing and reinstalling the shell requires unplugging/plugging the 2-conductor cable and after several removals/installations, the small leads on the smoke generator broke. I think I need to come up with a different way to make electrical connections to the smoke generator. Maybe use another light bulb socket and just plug the leads of the generator into the socket just like the light bulb leads but it would have to be located right where the screw is located for the light bulb PCB. Some more thinking required on how to insulate the smoke generator from chassis.

Nice conversion!

I did a similar Primex 3193 this week, but chose to go with the ESU Lokpilot V4 and Hamo magnet, keeping the original motor armature and brush plate, as I was aware that the standard 60944 kit does not fit properly on this loco.

My conversion went fairly well until I tried to get the loco body back on. I just could not find a position for the chokes which didn't foul the inside of the boiler/firebox/cab. In the end I just removed them and connected the wires directly to the motor terminals. I think the original brush plate doesn't give enough clearance, so I might try to fit the chokes closer to the decoder and extend wires from them.

I'm happy now with the performance of the loco, but I found it hard to get a good CV setting for this motor, as usually seems to happen for me with the Lokpilot V4 decoders. I used to find the V3 much easier to program. I try to stick to Marklin motor and decoder kits where they are available, for the ability to just stick the bits in and watch it work flawlessly!

The correct motor upgrade parts for a 3048, or an F800, or Primex 3193, etc, are provided by Märklin as part number E188838.

This set is available to order from Märklin dealers, or on German eBay at a considerable mark-up in price! The set of parts cost me 14 Euros from my dealer in Germany (just a couple of weeks ago), but they are 40 Euros or more on eBay.

I can confirm that the parts fit and work extremely well. Obviously, you need to buy a decoder as well, a Märklin mLD or mSD, or an ESU equivalent would be suitable.

I have just upgraded a Primex 3193 so far, but I'm going to do an old F800 when I have time.

Thanks Nigel,

I suspect this kit became available when Marklin produced their own 30080 digital version of the old tooling Br01. Previously there was no way to get the Marklin 5 pole motor to fit without chopping the brush plate about. It's a shame I wasn't aware of this kit a couple of weeks ago. I would much rather have gone this route instead of the Lokpilot and Hamo magnet combination. However, there's no point in changing a working loco at this point.

The kit E188838 is currently listed on ebay.de at around 35 to 55 euro but shipping may be an issue outside Europe unless you bought something else from them.

The kit pictured on ebay.de is what I had purchased some time ago to convert my 3048.

I am going to ask AJCKids to see if he can get the kit as I have a couple other locos I would like to convert.

Here are a few more pictures of my conversion:
