The next phase of construction for the KC Streetcar Riverfront Extension project is connecting newly installed tracks to the existing downtown route. In order to do this, in late January 2025 there was a temporary suspension of streetcar service and Riverfront Extension crews closed 3rd street from Walnut Street to Oak Street.
Necessary Streetcar Adjustments
Updates and adjustments are a key part of maintaining fast and efficient streetcar operations with the expanded route. As part of the Riverfront Extension, the team will install six new track switches. Track switches allow the streetcar to easily change paths. While four will be traditional track switches where a lever guides the streetcar toward either the main track or a diverging one, a diamond and an equilateral track switch will also be installed.
What Is a Diamond Track Switch and Where Will It Be Installed?
A diamond track switch is a junction where two tracks intersect to form a diamond shape. Diamond track crossings allow for smooth transitions between intersecting tracks, preventing the need for over- or under passes. They are a more cost-effective solution to track expansions and adjustments, provide more flexibility in direction, and help minimize delays at junctions where a streetcar switches paths.
The diamond at the intersection of 2nd Street and Grand Boulevard will reduce congestion out of the Kite Singleton Streetcar Vehicle Maintenance Facility. Streetcars will be able to turn south to go toward the River Market/City Market or north to go toward Berkley Riverfront.
What Is an Equilateral Track Switch and Where Will It Be Installed?
An equilateral track switch, like a diamond track switch, is a type of special trackwork that allows a streetcar to change paths. Rather than two intersecting tracks, an equilateral switch features two symmetrically curved routes. It is most beneficial in locations where straight track ends or cannot continue and a streetcar has two directional options of equal importance.
An equilateral’s design allows a streetcar to travel at maximum speed through a turnout, preventing unnecessary streetcar delays. The new equilateral switch at the corner of 3rd Street and Grand Boulevard, will allow the streetcars to move more efficiently through the intersection. The biggest difference will be streetcars having the ability to turn right on 3rd Street when traveling south on Grand Boulevard from 2nd Street. After installing the equilateral switch, crews will build additional tracks on the Grand Boulevard Viaduct/Bridge, and connect to those already built in the riverfront.
As the KC Streetcar Riverfront Extension progresses, these critical track adjustments will enhance operational efficiency and improve connectivity across the expanding system. The installation of both the diamond and equilateral track switches will streamline transitions, reduce congestion, and support the long-term growth of the streetcar network. While temporary closures and suspensions are necessary to complete this work, they pave the way for a more seamless and flexible streetcar experience for all riders.
