Here's is the old Laconia Car Company factory turned into office and restaurant space. It was founded by Charles Ranlet in 1848 and became the largest manufacturer in the area. They manufactured freight and passenger cars for trains, and later electric streetcars and trolleys. There are still a few examples being used or in existance today. Check this website for a more detailed history and some photos of the cars.
