Marx made several variants of its Girard station. One was just a tin building. The better one had lights. The best one had lights and a train whistle. Here’s how to wire a Marx Girard station with both lights and the whistle. This works on the Oak Park station too.
I wire it a little bit differently than Marx did in its instructions. Marx’s way works, but can cause the light to dim when you push the whistle button. My way doesn’t dim the lights.
