Squeaky’s Trains & Things LLC was founded in December of 2019. It was started by our family that has been in love with everything, trains large and small, driven by creativity since we were born. We grew up playing with model trains and watching, learning about and studying different aspects of magnificent locomotives on a daily basis and today we still do.
It also has helped us get through rough times while dealing with being diagnosed on the autism spectrum. Trains and creativity have always helped calm our daily lives while also becoming self-taught on making designs and artwork.
With this our family activity that grew into a really big hobby! We realized local train stores were barely available and we also wanted to start offering other model railroading fans our self-made creations for their enjoyment. We want to help the community around us by providing model railroad supplies and continue the legend of the greatest hobby on earth, model trains and railroading!
