So I recently inherited some HO scale 3 rail Marklin stuff that is from the 1950' s direct from Germany when my great Uncle was stationed in West Germany.

The rail, locomotives and cars all have oxidation from being stored in a airplane hanger all these years. I have a transformer and it looks to be a standard circle of track.

1. What's the best way to remove the oxidation without ruining the models/track?

2. Basic repairs, suggestions before I plug the transformer in and try and run a locomotive?

Recently aquired a 484 brass loco and tender. Unfortunately the connection from loco to tender is in a bag with loads of bits. These include springs washers small screws etc.

i have tried various combinations of washers and screws but once on the track it just comes up with a short.

i am DCC and would love for someone to tell me what sequence i can connect the two together with the screws and washers and springs etc

Hope this makes sense

A bit over four years ago, we put together something called the “DCC auto-reverser” out of an Arduino, an LCD shield, and a motor shield. We designed it for the St. Louis Railway Prototype Modelers’ meet to just operate a train back and forth on our short test track, stopping and reversing the engine when it tripped a sensor at either end. We wrote up the build so that others could make their own, built one for Scott Thornton and his Milan Branch layout, and that was that.
