What scale is this and is it on your own layout?

It is HO scale. and yes, it is on my layout.

My first greman Steam Locomotive was 70 class Locomotives but it was Freshmann .

Ah, you mean Fleischmann. And this IS from Fleishmann but it is for alternating current operation, which is why it has a pickup shoe on the underside. Fleischmann, Roco and several other DC model railroad companies have made AC variants of their HO scale locomotives for those that own Marklin made track.

won't work on my tracks
as these use center pins in the middle of the tracks

Yes, I know you are a fan of the two rail system. But the Alternating Current track with its center rail made up of center pins makes setting up a layout a lot easier without the need for complete wiring.

well thats what we use in NA mostly
only 3 rail systems are Lionel & Marx O gauge

I would do a controversial DB train set but naah

The early Marklin HO track actually had a solid center rail.

neato Didn't know that

It really is neat.

It was a Fleischmann DC . It looks like Roco, Fleischmann used same bodies for AC . But Fleischmann track has power pickup for DC but only for Switches, Turntable, etc.

Roco uses the former Fleischmann body tooling. Several years ago after a bank in Austria bought Roco and Fleischmann to keep both companies in business, it was decided that Roco would stop making N scale items while Fleischmann would stop making HO scale items. Fleischmann got the N scale tooling that Roco used to own while Roco got the HO scale toolings that Fleischmann used to own and both companies, now focusing on only one scale each are putting to use the toolings that they got from the other company. As such, in recent years you will have seen Roco releasing items that look just like ones that Fleischmann used to make.

yes. I have been see favorite guterwagen & Kesselwagen

I am glad the items are still being made.
