Greetings,
Some time ago, I traded for a 1938 4-4-2 Märklin Tenderlok TCE 70/12920 which would not run
and sat on the shelf in fear of an expensive rewiring job until I tried DC (Gleichstrom)...it runs perfectly
on DC...a thing of beauty and a joy to behold!
I was told that the motor is absolutely factory, not a hobby conversion, but
I have been unable to find any information on the history of Märklin DC. I would feel better
if I saw a reference, something in black and white so that I know I am not dreaming.
I am new to Märklin and any help would be greatly appreciated,
Rich

Hi Rich,

Welcome to the forum...I'm not much of an electrician so I'll leave your question to some of our other forum members to answer. Although I seem to remember Marklin had both AC and DC at certain times for the O Gauge.

If your loco does need to be rewired or fixed mechanically then that is certainly something I can help you with. BigGrin

Best regards,

Paul

PS here is some Marklin O Gauge literature:

Hi Rich,

All Märklin-locomotives with a "70/" in their number are for DC-operation. These locos are reversing by pole-switching like most modern H0-trains except for Märklin. The system was produced from 1935 until WWII. The locos can be used together with "66/" or earlier series. Their motors work fine even with DC and they operate like before (with AC).

Regards

Markus

Many thanks for the links, Paul. I have made some progress
finding out about the history of Märklin, bits and pieces of
information here and there, and it looks like a puzzle I will
have to solve like a dectective, but both AC and DC motors were definitely
part of the Märklin line in the late 1930's.

Hi Markus, so, the "70" series is all DC, right?
I did see a 4-4-2 Tenderlok ebay item in the "66" series
listed as "Gleichstrom"...this makes the "66" series, what?
By the way, is there a Märklin history available in German?

Again, thanks for the help,

Rich

Hi Rich,

Originally "66/" engines have motors which work with AC and DC. The locos reverse when the the electric supply is cut off. 1st start: forward, 2nd start backwards, 3rd start forward.... . After WWII when better rectifiers and diodes were available many 66/ locos were converted to DC-operation (reversing by pole-switching). When a "66/" - loco is offered for Gleichstrom (DC) this is such a modified engine.
A first overview over the history can be taken from Wikipedia: http://de.wikipedia.org/wiki/M%C3%A4rklin

Regards

Marksu
