Older Train set Marklin SET-HO 3185=S+E. I have been given a train set that was purchased

Answer 1

 What are the Voltage and current specs for Marklin HO AC locomotives? I want to use my own transformer and need to make sure it provides the right voltage and current to the track. I live in the US.

Answer 2

Many of Marklin's HO sets were sold without transformers.  This is because Marklin shipped their products to countries around the world, each with its own voltage/Hz requirements.  So Marklin's strategy from 1945-1980 was to market its HO sets with just train and tracks, and to let the consumer then decide what transformer/rectifier to purchase separately (i.e. 110 volts for Canada/USA, 220-240 volts in Europe, 100 volts for Japan, etc.).  The most important thing to note, however, is that Marklin's HO system operates on three-rail AC only, whereas many other manufacturers are 2-rail DC.  You must therefore buy a Marklin transformer with the voltate appropriate for you country.  The Marklin Set 3185 is, I believe, the set with the 4-6-2 DB steam passenger locomotive with three passenger cars, as well as M-track for the S+E track configuration (i.e. oval plus two switches to create a siding).  M-track is the metal-based track.  This set was produced largely in the 1970's until around 1980.  It is very desireable if it is in good condition.
