The Walking Locomotive is a moving train with legs, which appears in the first mission of Metal Slug 6.
The Walking Locomotive is a vehicle developed by the Rebel Army to send supplies to the soldiers on the front line. After the destruction of the Supply Train (Metal Slug 2 & X), the Rebel Army needed a new means of transporting supplies. The result was this tall and very well armed Walking Train.
A modified train, it is armed with several heavy weapons, backed by Rebel Infantry members providing supporting fire. Destroying some sections of the vehicle will give you supplies such as food, ammunition, or even POWs - one in particular provides a Metal Slug. It is very long and may require two players to destroy all of its parts. It is a very fast and welled armored but a Heavy Machine Gun could tear it up easily. Grenades or a Slug's cannon can be used against it for increased firepower. Two sections have large turrets firing rockets. Destroying all of the parts in succession will drop lots of coins.
- Even if the front is destroyed, the train continues to move. Presumably the remainder continues on auto-pilot.
- The Iron Cab in Metal Slug Attack also fires a powerful laser beam, using Tetsuyuki's cannon sprite.
