Toden Arakawa Line km trip in 50 minutes. The gauge is . The line is fully double-track, and draws 600 V electrical supply. Two Toden Arakawa trams (one in revenue service, the other undergoing brake testing) collided on June 13, 2006 near the Minowabashi terminus, injuring 27 people. The Toden Arakawa Line operates in northern and eastern Tokyo outside the main tourist areas.

Arakawa grids grid cell, e.g., at the grid center or at the grid corners. The Arakawa A-grid is the only unstaggered grid type. The "staggered" Arakawa B-grid separates the evaluation of the two sets of quantities. e.g., one might evaluate velocities at the grid center and masses at grid corners. The "staggered" Arakawa C-grid further separates evaluation of vector quantities compared to the Arakawa B-grid. e.g., instead of evaluating both east-west (u) and north-south (v) velocity components at the grid center, one might evaluate the u components at the centers of the left and right grid faces, and the v components at
