Hi.

I have a c-track h0 setup coming from a Märklin 29166 start up kit which included an IR controller ref 253391.

After that came a BR55 37550 (I intend to upgrade to another decoder when I fell more confident, but that is for another topic), and an Ae 3/6 II ref. 37514.

I could control all of the them with the 36VA power supply and the IR controller, but it only has 4 function-buttons + lights.

In order to solve that, the next step was the acquisition of a second hand ms2 Trix branded 66950 + Märklin 60113 digital connector box. Now with a simple track design with no electric accesories on track, only 3 locos and passive wagons, that setup runs fairy well with the same 36VA power supply.

2 weeks ago I received a Trix branded BR 185/Traxx 2 ref:22656 as a birthday present, but since then I could not get it no be seen by the ms2.

At first I thought the ms2 I purchased was defective, so it was sent to the technical service to have it checked and upgrade the firmware to the latest version, 3.148.

The loco is not seen by the IR controller either.

The ms2 sees the Ae 3/6 II as mfx blinking in the screen. I thought it would be the same with the 185/Traxx 2, but mfx, dcc or MM search from the ms2, even the manually configuration with the factory settings achieves nothing. It simply stays on the track and does nothing. I checked the dual supply (power coming from tracks or pantograph) and it stays firmly in the right position.

I have checked the big capacitor inside the digital connector box, and correctly measures 4700 microfarads. There are no signs of corrosion.

At this point I have neither ideas nor enough experience to solve this, so if you could lend me a hand, that would be much appreciated.

Thank you.

Regards.

Víctor.

Thank you for your reply.

I only have Märklin tracks.



It does not have a slider... can I buy and install one?

EDIT: Ok, I have read more topics in the forum, and it seems it needs a separate 2 rail ring in the circuit, or a non trivial conversion of the loco, so i think i will return it and try to find the märklin 3 rails model.

Thank you again.

What a rookie mistake

If you want to do it like Märklin do, get a bronze plate as spare part to make a contact for the centre-rail slider. It is also possible to solder the wire directly to the bronze spring of the slider.
Some of the locos I converted already had a tunnel for the centre-rail wire, with some I had to drill a hole.
Swap three or four wires inside the loco, not really complicated.

The Trix Traxx (not Hobby) has slots for the slider to clip in and the slider comes with the wire which can be slotted into the hole in the bogie.

Hello Mike.

Could you point out in the photo I uploaded where should be the slot for the slider?

If I get a Trix Traxx again in a mid-term future when my knowledge is enough (lots of assumptions tbh ), I might try to do the conversion...
