Hi Marek
When you tested on DC did you use a Fleischmann controller with MSF?
That will give smooth running when the loco is not really that smooth

If the brushes are unevenly worn or coated with oil they can cause intermitant slow running on DC and DCC
The BEMF will try to compensate , with the result an uneven speed
Try turning off BEMF and test again.

replace the brushes and clean the motor interior -then test the loco

Turn the BEMF on again and test
Hope this helps
Regards Zmil

Hi All
This topic is very informative

So many of the older loco's can be a little difficult to get running smoothly at slow speed

I think we need a DCC fine tuning guide! - a topic pinned to the DCC page for reference

Hi LF
I noticed a couple of weeks ago,someone selling a large quantity of Fleischmann motors on Feebay
(about 20) most complete with wheel sets for tender driven loco's
so it must be a viable option

The BR 94 that Marek has , must be a 4093 ( 94 956 ) is not that old , made between 1983-1993

I have converted much older Fleischmann Loco's , but as Richard says -not the best on slow speed on DCC -they may be bullit proof but thay do take a little fine tuning , but I have had some work very well even on default settings
with the TCS BEMF decoders I'm still amazed at how good , that BEMF is
