This part wasn't meant to be taken apart, but it is possible.

    Thank you for your answer! I managed to open the train base using the poorly illuminated video tutorial and three kitchen knives. It is surely the easiest, but also most dangerous way to do so. The train did not work because of a loose contact to the motor.
