First time posting and forgive me if this has been answered. started building my layout and i have an old dc train set with the out of the box transformer with forward and reverse (move throttle to right train goes forward, to the left backwards). I have some old 1122 switches that i was going to modify and make constant voltage but after research here on this site i am not sure it will work with the reverse option on my transformer. When placed in reverse the outside rail become positive and middle rail is now negative.
Since the capacitors negative leg is connected to the ground rail, will the reverse mode when applied send voltage back into the capacitor and explode it?
If so what is a possible work around?

The best place to find the answer to your question is to contact the guys down the hall at Classic Toy Trains. That said, I grew up with 027 trains and really got a kick out of my manual Marx switches. You could "bend the iron" just like the prototype! Best of luck with your project.
