The primary difference between the M9 and M9A trains lies in a few features. The M9A trains feature additional amenities such as USB ports in each AC outlet, powered bathroom doors, stainless steel urinals, and Gorilla Glass side windows that prevent hazing, fading, and crystallization. The M9 trains lack these specific additions.
