We were walking around and found this by accident, were invited in by staff. Ended up being the highlight of the day!! Staff was so knowledgeable and interesting!

We wanted to visit since the website says it is open on Sundays, but the gate is locked and there is a sign indicating the facility doesn't open until May 2022.

It was only fitting I took the train to So Norwalk train station to visit SoNo Switch Tower Museum. about a 10 minute walk. Free to visit but gave a donation! 3 floors to explore. Staff on each floor explain the in and outs how the switch tower works. While there commuter trains past by. Staff was very friendly and helpful. only open on weekends.

The SoNo Switch Tower Museum is a great example of early 20th Century railroad technology preserved in working order. The three-level tour has the main switch room in the upper floor (with a great view of the adjacent railroad junction); laid out as it was when in use. You get to try out throwing the switches (hooked up to display tracks, not the actual railroad), so you can see the level of effort needed to align a train's route (and learn why these were called Armstrong switches).The other floor show more the mechanical computer controls used ~100 years ago to make the train rides safe; you get a sense of what electronic computers would eventually replace. There's also a New Haven-themed gift shop. A must visit for anyone interested in railroad technology or history.

It was very cool to see the switch tower and learn about how train move from one track to another. We learned about the communication between stations and the history of trains in the area. This attraction is free with suggested donations to keep the place going.
