I believe that I read in one of the messages That the Speed control for
the 9 volt battery marklin powerepack
offers excellent low speed control. Is it better than the control provided
by the Blue marklin pack?
If so can it be hooked directly to either the controlled or uncontrolled
out put of the marklin pack.

that I recommend the Joerger Fun Set speed control is ONLY used with
a 9V block battery because it does not have sufficient short-circuit
protection for a stronger power source. So please do not connect it
to the Märklin pack.
I also wrote that I have a prototype version of the same circuit that
IS suitable for a stronger power source, primarily for use in
briefcase layouts. I hope to have news of that product in about two
weeks time. But it needs a smoothed DC supply, preferably regulated;
there are suitable mains adapters available quite cheaply.
I have been toying with the idea of producing a modified version of
the briefcase product that would use a Märklin controller as power
source. By means of high-frequency pulse width modulation (as used in
the latest digital decoders) it would control the speed smoothly over
the whole range. I've made a prototype which works satisfactorily,
but am not convinced that it is worth "saving" the Märklin
controllers when a relative cheap mains adapter works as well. What
do you think.
I am sure there are other commercial products that members will
recommend too! Jeremy.
