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 in Metal Slug 2/X, the Rebel Army needed a new means of transporting supplies. The result was this tall and very well armored walking train.
A modified train, the Walking Locomotive is armed with several heavy weapons, backed by Rebel Infantry members providing supporting fire. A few sections have large turrets that fire homing rockets. Destroying some sections of the vehicle will drop supplies such as food, ammunition, or even POWs; one section in particular provides an SV-001. It is very long, fast, and heavily armored and may require two players to destroy all of its section. A Heavy Machine Gun, Grenades, and the SV-001's weapons can tear it up easily. Destroying the entire Walking Locomotive causes each section to drop tons of coins.
In Other Games
Only the caboose with the turret appears as a playable unit. As such, they are called in the game as Cabs. They are smaller and each contain a weapon in its undercarriage.
The Iron Cab returns as an SSR Slug with the same appearance as in Metal Slug Attack. Instead of holding a weapon inside, it deploys Rebel units by dropping from its underbelly.
|Iron Cab: The original variant. Launches missiles and also carries a laser cannon in its undercarriage.|
|Frozen Cab: A variant of the Iron Cab developed for Beatriz, the Frozen Cab has an ice cannon and is much more durable than the original variant.|
|Blaze Cab: A variant of the Iron Cab developed for the Blaze Brigade. It is equipped with a long-range flamethrower that is particularly effective against Invaders.|
|Fight Cab: A heavily modified variant of the Iron Cab. Uses large wheels instead of legs to run over enemies while also slamming a large Kraken-like worm onto the ground. It is piloted by Sylfie. Appears in Metal Slug Attack.|
- Even if the front is destroyed, the train continues to move. Presumably the remainder continues on auto-pilot.
- The Iron Cab and its variants in Metal Slug Attack uses the Tetsuyuki's cannon sprite as part of the Cab's special.
