I was wondering if anyone here has converted any Liliput DC to run on the Marklin AC 3 Rail system? The particular one I am interested in is the Liliput 104223 BR 42 in DC. I do understand that Marklin made a BR 42 as a 39161 and Trix as well, however it is just not the same Loco. If anyone has done this conversion I would be interested in the results and difficulty.

Thanks in advance,
Bob

Hi Bob,
I've converted several Liliputs to 3L, from both Wien and Bachmann.
The old (Wien) ones, normally have a slot in the tender, already prepared for the installation of the pickup shoe. You'll probably have to make a thread but the whole should be there.
New Bachmann Loks lack that slot, so you'll have to secure the pickup shoe under the Lok. I use hot-melt adhesive. A wire needs to be installed from the pickup shoe to the tender.
Also, you'll have to isolate the motor from track (as you must do in all conversions) and to join both track wires in order to take ground from both rails.
Also, you'll need to reduce the light's voltage, since your Lok is fitted with 12V bulbs. You can do that either by CVs or by installing a Zener diode in series with the bulbs.
Not too difficult, but you need some time to do the conversion.
Regards,

some weeks ago I mailed to a german shop to ask for liliput material in 3 rail..they d-told me they only have 2rail.but that it would be possible to convert it into 3rail.. so I guess moslty its possible to convert liliput dc into ac..but if it is an old liliput loc from before the 80's, then I do not know..
cheers
