Trix Trans-Pennine DMU - converting to DCC

[dave55uk]

I'm trying to DCC my Trix Trans-Pennine unit and I'm not having much luck.

 

Has anyone DCC'd such a unit please?

(And who would care to tell how they did it).

I did but I ditched the Trix motor unit and installed a Bachmann DMU motorised chassis in one of the trailer coaches.

 

Trix Class 124 project

Thanks Darius, good to know it can be done.

 

As I have never tried doing this sort of thing before, could you

tell me which Bachmann DMU you used - and was it the complete

chassis or just the motor bogie? And were there any particular pitfalls

to be aware of?

 

I'm not too bothered about underframe detail just as long as I can get

the unit running (on DCC).

As I recall I fitted a Bachmann DMU motor block and bogie to the Trix coach chassis after cutting a hole for the motor bogie in the coach chassis.

 

I’ll see if I can dig it out of storage and take some pictures of the installation.

 

Cheers

I used a Lenz Standard + decoder in mine.  It was hard wired.

 

Unfortunately it was a few years ago so can't remember if I had to do anything special. 

Will dig it out and see if i can take some photos

 

Ok so taken a look and I did actually add an in-line 8 pin socket so I could remove the decoder should I want to.

The wires are also a little bit oversized so I may take the opportunity to rewire whilst it's apart.

 

You will see in the two pictures where the grey and orange cables from the decoder need to be connected.  

The original cables from the pick-ups need to be disconnected from the motor and connected to the red and back cables on the decoder and then if you want the headcode light working use the white and blue cables. 

 

I stuck the decoder to the corridor connection end of the seating and ran the cables above the seats.  I removed the interior lights on mine.    

I also added an extra pick-up to both bogies.  As originally wired there is only one pickup on each bogie.

 

Sorry couldn't get theses to display with the correct rotation once resized

Thanks beejack, those pictures could be very helpful.

I'll dig out the unit and have a look.
