Ato

The Ato cars are the cargo of a robot train. Unlike standard cargo, the Atos can move without being coupled to a locomotive, allowing the robot trains to move around without having to worry about losing their cars.

Abilities
The Ato cars house the upgrade units for most robot trains, which deploy when the cars' respective robot train gives the command "Launch my units!". Jeffrey and Selly lack upgrade units, while Jeffrey's Ato cars mainly allow him to transport materials. Selly's cars contain a special wagon that keeps Becky with her on her travels.
