So far I have a starter set BR78, and I was looking for a smaller tender engine in affordable price. This BR38 came across me on eBay.
I received the loco, the stand in the original box but nothing else. I am missing all documentation, instructions. I was not able to find it on Marklin.de either (maybe I was looking at the wrong place). Just unboxed it, not tested yet.

Please share any info about this loco, or experience if you have any. Judging by the 4 digit product number, this is probably an early model, and the sound decoder is probably fairly basic. I am thinking that this loco would be a canidate for an ESU Loksound upgrade, or maybe even a smoke generator as well.

I have a few 3 axle compartment coaches (see my recent post: Replacement for 5605 light kit), and the plan is to have these coaches for this loco. If I understand from the interwebs correctly, BR38 with the tub tender is a later epoch (as opposed to the original smaller tender) so the 3 axle coaches might not be epoch-perfect for this version of the locomotive.

It took some time to actually test the engine. Since I have no documentation I just assumed it has an early Motorola digital board with sound, but 5597 does not appear in the digital database. When I looked at the board in the engine, I realized that this must be an AC board with an analogue sound module.

The big white relay was a clue that this is likely to be AC engine. I tried with an AC power supply and she is running, and there is a basic chuff sound and a reed switch in the tender activates a whistle.

Am I correct that this is an AC board? I don't see any dip switches to indicate that it also supports Delta. But again I assume something is either AC or Delta digital not both.
I yet to test the motors, but I am hoping that is a DC motor (for future ESU retrofitting).

Also I could not figure out how to take apart the tub tender. It feels like the top can be removed, but I don't see any hidden nuts. I want to check were all the different wires go, especially that one of the wire does not appear to be connected. Any of you know the disassembly steps for this tender?
