Train (obstacle)

Trains, also referred to as N64 Expresses, are stage obstacles in Kalimari Desert throughout the Mario Kart series. They are red-and-black coal-powered steam locomotives with five passenger cars in Mario Kart 64, and three passenger cars in Mario Kart 7 and Mario Kart Tour.

A similar train called the K64 appears in Paper Mario, with the music that plays when Mario rides it being an arrangement of Kalimari Desert's music.

Mario Kart 64
The Kalimari Desert course in Mario Kart 64 features two trains, both of which travel along an elliptical track that the player crosses twice; at each crossing lies a crossbuck and a set of two lights that flash if a train approaches. The player flips over if they hit any part of the train, including the passenger cars. In VS Mode for two players in Mario Kart 64, the train has only one passenger car, while in the Grand Prix for two players, as well as in VS Mode for three and four players, all cars including the tender are removed.

In the Wii Virtual Console release, the train's wheels are colored black instead of red.

Mario Kart 7
Trains reappear in the Mario Kart 7 rendition of N64 Kalimari Desert, once again acting as obstacles for drivers. They can be taken out by driving into them while under the effects of a Super Star. In the multiplayer mode, one of the trains is absent.

Mario Kart Tour
In Mario Kart Tour, trains launch drivers up in the air while providing them a Jump Boost. They can be taken out by hitting them with a Super Horn or by driving into them while invincible or under the effects of a Mega Mushroom, granting points in the process. Aside from N64 Kalimari Desert, one train also appears in N64 Kalimari Desert 2, moving at a much lower speed than those found in the former course. If a player waits long enough after a race, it can be seen that the barriers found at the second intersection in the normal and R variants, or at the first one in the T variant, do not affect the train.

Amsterdam Drift features two course elements that act like the trains in N64 Kalimari Desert, giving drivers Jump Boosts when touched and "Train" points when taken out. One of these is a train resembling a, which travels along a viaduct in-between the Amsterdam and segments of the track; the other is a tram pertaining to the Amsterdam , which moves back and forth along a short portion of the track near the finish line.

Other trains with gameplay roles in the Mario Kart series
In Mario Kart 8, Mario Kart 8 Deluxe, and Mario Kart Tour, there are flying trains that appear in, several bonus challenges in 3DS Rainbow Road and Merry Mountain. Toads ride on them and throw coins or rings on the track for the player. They can also carry Star Rings that can be glided through.

Trains also appear in the background of Sydney Sprint, Sydney Sprint 2, and their variants. The passengers on the train will throw items such as Green Shells, Mushrooms, and Bob-ombs onto the road.
