[CanPassRail] Re: Switch motors outside Union Station?

 

I should have mentioned that the switch machine was designed in the 1920s, so it would have been relatively new technology when they were installed. The model became the most popular design in the industry, and variations of that model are still sold today. So almost 90 years later, it's still competitive. Not bad longevity for a product, when you consider that the life cycle of things like mobile phones and computers is probably less than 5 years these days.
