I don’t come across burned-out light bulbs in Marx trains very often, but it can happen. When you need to replace a missing or dead bulb, you have some options.
Marx, like its competitors, used a standard E10 screw base in all of its trains and accessories that I know of. It’s best to never say never with Marx, but standardizing on E10 was cost-effective so I doubt there’s any variance. The question is what voltage.
