Hi all!

Before anybody trys to convert his 9V train motors, I have to jump in and warn
that these 9V motors are really to weak to "pull a fish from a plate" (as we
say here).
If one exchanges the rubber bands of the wheels against the rubber bands from
Lego-Minifig-bicycles, it is somewhat stronger on 12V track, but still it is
basically running on the outer rims of the wheels and tends to slip.

For the converted 12V 7865-motor I fear it suffers even the worse under these
slippage effects. Without rubber these wheels will probably never be able to
pull a train like a Santa Fe engine with 2 (or more waggons) through a point
combination.

With such a converted motor one may pull 2 waggons on a oval track, but
combinations of curves and points (or use of 12V waggons) make things very
unreliable in operation - the train may stop due to 'overload' then...

I was not too happy with any of mine experiences: it works for very short
trains and some extra weight over the motor helps as well, but after I
converted 5 motors I stopped and decided to leave the 12V train system for
ever.

The 7750 and 7740 are now shelf models only and all I have left is a small mini
layout in 12V for reference use of remote controlled stuff and for picture
taking purposes.

Maybe there are early Lugnet postings of mine in which I tell about my love to
12V because of all the nice remote control equipment etc, but in the meantime I
am a convinced fan of the 9V system. It offers 100% play value and 100%
operational reliability. And at our shows we need only some 10 minutes to put
the layout together and bring the first trains on their way. In 12V this has
been a process of hours instead....

Leg Godt!

Ben
