Hello, I recently acquired a new LGB 28006 Ruub locomotive (pictured below), it comes with MFX decoder and many functions, but to my surprise it doesn't include energy storage capacitor bank. it constantly gets stuck on the turnouts. Has anyone opened this to see if the LGB 55429 capacitor back can be hooked up to the main board ? is there room inside for it ? I searched online and did not find anything on this....it's a relatively delicate locomotive and don't want to open it up and be disappointed. I usually add a capacitor bank to the cheaper loc's and that does the trick, was expecting this one to have one for the price $$$.

TIA

Thread 'Keep ALive in Newer LGB MFX locos'

Hi,

I've tried researching this on the web but hit a brick wall.

Do the latest/recent MFX LGB locos come with a stayalive buffer? If not is it possible to fit one?

I have seen suggestions that it is possible to fit an LGB 60974 MFX Power Buffer, but the Marklin web site has very little detail on this product.

Most of my locos are older units upgraded by me with Zimo and ESU decoders with no problem, its that I'd like to get some newer locos, but dont fancy binning the new decoders.

Thanks in advance

I install super caps in engines and LGB sound units. Be sure to use add a current limiter in the charging wire as super caps can draw a lot of power (read current) when first turned on.
I make my own for Zimo as they have a built in circuit to limit current when adding super caps and is limited to about 16 volts for storage. So all you need is to place super caps in series to go slightly above 16 volts for Zimo decoders.
 
I had a new one of these that did not run too well so I checked that all the wheels were picking up power and a couple of sliders on the back of the wheels were not connecting to the back if the wheels. Worth checking continuity each side with a meter to see if that is an issue with yours. Once mine was sorted it ran superbly.

I can endorse this as I had an early one which was only picking up current on one wheel on the firemans side Off with the bottom and carefully rearranged the pick ups and viola everything was fine
 
For my part i've finally installed the 55429 in an old E10, with 55029 decoder, because, there were poor connections at the points, causing the locomotive to stop; now, it runs smoothly and precisely without any jerking, a great purchase !

Somewhat related......

There has been quite a bit of discussion in the German language G scale forums about issues with the DCC power buffers on the locos issued by LGB in 2025....... many appear to be faulty!
 
I ended up just cleaning the tracks a bit before using the Ruub, seems to have done the trick, occasional hiccups on the turnout if I go super slow so at some point I will open it up and see if there is room for the cap.

It seems LGB listened, all LGB models from late '25 forward will come with storage capacitors installed at factory at least anything more than $500. I have a new 24451 that comes with factory installed capacitor, no issues. The LGB does not use super-capacitors, super-capacitor is a non-linear device (kind of like a hybrid between a battery and a capacitor) so it requires some consideration. I like to use LGB brand components only, in my experience they work better with LGB locos.
