Also known as: 電車でD, 電車でD(n次創作)
Densha de D (lit. "D on trains") is a parody of Initial D, right down to the characters. The main difference is that instead of Cars, Densha uses Trains.
It is perhaps best-known for a scene in which Fujiwara Takumi, near the end of a a race, forces one of his train's axles onto the opposing track, in a technique described by Takahashi Keisuke as Multi-Track Drifting (Meme).
