In 1890, the two cities were connected with a railway along
University Avenue, the first of four rail lines linking them together. A merger of the two city systems, the St. Paul City Railway Co. and Minneapolis Street Railway, formed the Twin City Rapid Transit Company. It went on a building spree, quickly doubling the amount of electrified track in the system. The company continued absorbing smaller competitors for the next 40 years. In 1898, the company began a transition to using company-built streetcars and machinery (such as
cranes and
snowplows) rather than purchasing the cars from other companies. The first such car was built as a personal streetcar for company president Thomas Lowry, although his was a special-order. The car featured one end with large windows, to make the scenery more visible. This car was used on special occasions, such as the opening of new lines and a visit by United States President
William McKinley. TCRT built some of the largest streetcars in the country. The Twin City Rapid Transit Company got into the business of building street cars at its Nicollet Shops in 1898 after concluding that cars it was operating from Eastern manufactures couldn't hold up to Minnesota's harsh winters. By 1906 they opened a manufacturing facility at its Snelling Shops where they not only manufactured cars for TCRT but also Chattanooga, Duluth, Seattle and Chicago among others. These cars were larger than traditional streetcars, being long and wide. Old track was also upgraded. In the early days, a number of lines had been laid down with
narrow-gauge track. These were all
upgraded to (
standard gauge). In addition, the basic construction of the lines improved. The rails of the Twin Cities were upgraded to the most expensive track in the country, running
US$60,000 per mile. Tracks featured
welded (
thermite) joints, and were commonly surrounded by cobblestone or
asphalt. By 1909, 95 percent of the rails were of this type of construction. They were used until the company ended streetcar service. From 1906 to 1926, TCRT experimented with "streetcar boats." Officially known as Express Boats, they were steam-powered vessels with designs reminiscent of the streetcars of the day. The boats operated between communities on
Lake Minnetonka, but improved roads in that area hit ridership hard in the 1920s. Ultimately, seven were built, but most of them were scuttled in the lake in 1926. TCRT also expanded into the suburban
amusement park business by opening the Wildwood Amusement Park on
White Bear Lake and
Big Island Park on Lake Minnetonka. The park on Big Island was serviced by three large
ferry boats from
Excelsior. As the rise of the
internal combustion engine in transportation grew, the Twin City Rapid Transit acquired several bus lines that began to pop up around the time of
World War I. They also acquired a taxicab company in the 1920s. When the transportation system peaked in 1922, it had nearly of track and 1021 streetcars. Rail extended a distance of about from
Stillwater on the bank of the
St. Croix River in the east to Lake Minnetonka in the west. For a time, TCRT was the largest employer in the area. It is rumored that anyone who lived in Minneapolis was no farther than (less than ) from the nearest station at that time. ==Changing labor conditions==
