Tram roundabout
 | This article needs additional citations for verification. (November 2019) |
A tram roundabout or grand circle is a circular rail junction for trams in the shape of a roundabout. A tram roundabout is able to provide the equivalent any-to-any connection of a grand union, but with a simplified tramway track configuration using one-way traffic, fewer turnouts and reduction in level junctions, at the cost of slightly more space. Trams may continue as one-way traffic in an endless loop around the tram roundabout junction.
A circular roundabout design is often used to allowing passing around a centrally-placed monument, or fountain, or small park.
