The Mount Tom Fire Station is a very old fire station. Its beginnings were not even in the station but rather pre-1887 there were in a house on North Main Street. At that point they were one company called the Mount Tom Hose Company number 1.
From 1893 to 1935 at least, there was the Mount Tom Hose Company number 4 housed in the station. This was a two horse hose wagon and steam engine. This hose company was organized in March of 1850.
From at least 1918 to 1957, there was the Engine Company number 4. This was a two horse combination hose and chemical wagon. They also had a second size Metropolitan steam fire engine of two horses.
