Rail Force

The **Rail Force** is a subgroup of the International Safety Committee later folded into Adventure Squad, consisting of a fleet of high-speed trains capable of transforming into robot forms. The group was conceived after careful observations were made of the prototype/eventual leader of the entire fleet, Echo 5, deemed his frame to be antiquated and his role in the Demon X conflict was considerably underfilled.

The original intent for the Rail Force was for the final units to be remotely controlled, with Echo 5 to be replaced by another unit and his data drive wiped upon their completion. However, the ICS's liaison for the project, Richard Murphy, was revealed to be deeply corrupt, and was scrubbed from the organization, with General Orion and ISC Chief Commander Felina Sanders replacing him as liaison for the project.

Adventure Squad Co-Leader Carson Lavern was responsible for much of the design, engineering and programming of the Rail Force's units, though while Murphy's interference resulted in the newest units being severely hampered in experience, Carson's rescue of Echo 5's data drive and the defection of Automon from Demon X's forces resulted in the entire fleet becoming quickly trained professionally. Automon's defection also results in the Rail Force totaling 11 members as opposed to the original 10.

All of the Rail Force units have special autocars that can move on their own and open their sides in order to transport large equipment meant for handling by robots. Automon is the main exception, with his cars merging into Brightstar (formerly Catastros), a large mechanical steed.

Carson built special data card slots into the abdomen section of every Rail Force unit meant to arm each member with up to 2 support modules, the sockets equipped with activation controls on each side. Unlike the rest of his teammates, Echo had free reign on what cards he can use from the beginning; Automon and Doc were initially limited to their own personal set while the rest of the Rail Force had them locked until they advanced enough in their training.

Because of Sodor's significant shortage in capable military power, all members of the Rail Force were sold off by the ISC to the Leonolds in light of the islands' significant reserves of Element Crystals and the Magic Railroad's Gold Dust (General Murphy, however, originally planned the sale just to get rid of them and spite the Leonolds, a plan that was immediately foiled when Carson made the purchase just as it opened). Given Sodor's practices when it comes to purchasing sentient rolling stock, however, Thomas sees this move as more of a family adoption, a viewpoint angle the group were more than willing to embrace. This also resulted in the team being integrated into Adventure Squad, with Echo joining Thomas and Carson as co-leaders of the organization.

## Units

1. Echo 5 (E5 Series bullet train; Leader)
2. Automon (Mechanical serpent-styled bullet train; Lieutenant)
3. Elton (E6 Series bullet train)
4. Hatchet (E7 Series bullet train)
5. Jetstream (800 Series bullet train)
6. Nitrox (N700S Series bullet train; Nozomi service)
7. Quint (500 Series bullet train)
8. Doc (Doctor Yellow inspection bullet train)
9. Harper (H5 Series bullet train)
10. Axton (ALFA-X experimental bullet train)
11. Cassandra (N700S Series bullet train; Kanome service)

## Support modules

The Rail Force uses a special modular weapons system modified from several conventional trains, able to form alternate limbs in addition to transforming into their own warrior modes. Although the modules are capable of being used by all members, Echo's experience and high aptitude means that he does not require using them to fight at full power. Automon and Doc are also exceptions, being able to combine with their autocars to achieve the same effect. Automon is able to combine with his cars into two configurations while Doc can combine with his own autocars both on their own and with Echo 5 into a stronger formation.

1. Paladin Module (Angon; Arms)
2. Sniper Module (Plinker; Legs)
3. Slasher Module (Barbarian) (Tomahawk; Arms)
4. Sky Archer Module (Fletcher (standard) and Bowyer (power); Legs)
5. Ground Trooper Module (Ronin) (Gladius and Sabre; Arms and Legs)
6. Infantry Module (Pierce; Arms)
7. Turbo Gunner Module (Flintlock; Legs)

## Adventure Squad units

Built around the same time as the rest of the Rail Force were three units directly affiliated with Adventure Squad. Unlike the main Rail Force mechs, these units are primarily oriented for rescue operations, general purposes and controlled weapons testing, and as such are borderline useless in direct combat, though they can hold their own against human-sized infantry.

### Units

* Spinner (East I inspection bullet train)
* Eli (N700S Series bullet train)
* Andrea (700 Series bullet train)

## Rail Force Titan Warrior

The Rail Force was eventually upgraded to allow all 11 units to merge into a larger combined form, with a similar performance to Carson's other combination designs. The **Titan Warrior** is capable of wielding all of the weapons in the Rail Force's arsenal, and is able to use Echo, Harper and Automon's sonic cannons simultaneously.

Formation:

1. Echo 5 (Left forearm)
2. Automon (Upper torso, head)
3. Elton (Right leg)
4. Hatchet (Left leg)
5. Jetstream (Back, wings)
6. Nitrox (Waist left half, left upper leg)
7. Quint (Lower torso, shoulders)
8. Doc (Left shoulder)
9. Harper (Right forearm)
10. Axton (Right shoulder)
11. Cassandra (Waist right half, right upper leg)

## Double Shells

The Rail Force **Double Shells** are copies of Echo 5's original body frame, though only one is built with said body's exact appearance. The Double Shells were originally built as non-functional replicas of the Rail Force simply as an art project by Lysander, but they were upgraded into fully-functional robot bodies during the battles against the Mechatroopers, which used the Double Shells as templates for their designs. The bodies use the same operating systems as the main Rail Force body frames.

## Notes

* The Rail Force models are all from Plarail's *Shinkalion Z* toyline, though the Titan Warrior was original to the series.
* The group's data cards and their activation slots are based on both the *Shinkalion* Shinka Gear and the transformation belts (also known as "Drivers") from the *Kamen Rider* franchise.
