[With the Level 2 Starter Train being upgraded to a Level 5 Train, there now existed 5 train carriages and 1 locomotive.]
[Moreover, due to the installation of the Accelerator Train Module, a pair of rocket propellers was installed on the train.]
[Unlike a train ability, which existed inherently within the train, a train module was mostly a device that was externally attached to a train.]
[In other words, you speculated that if the rocket propellers were destroyed, then the Accelerator Train Module would become unusable.]
[With both the Train Module and Train Ability already used, your attention shifted to the silver chest inside Carriage 1, where you and Jade stayed.]
[You didn't have to drive in the driver's cabin as the train will move regardless due to mandatory station stops. However, if needed, you and Jade could use your Train Conductor Authority to manually drive the train, but still can't make it stop or prevent it from going forward.]
