Barrel Train

The Barrel Train is Diddy Kong's unlockable kart in Mario Kart: Double Dash!!. It is a lightweight kart, but like Bowser Jr.'s kart, the Bullet Blaster, it has greater speed, but less acceleration. It is unlocked by completing the Star Cup in 150cc.

His train can be seen in Mario & Luigi: Partners in Time buried in Gritzy Desert. However, it may just be a coincidence, that this train looks a lot like the Barrel Train.

Another train named the "Barrel Train" appears in Mario Party 8. However, it is not the same train, as it is a full-size locomotive.
