The Tow 03 formation, which began operation in May 2017, is a prototype. Reproduces a different form from the mass-produced preceding vehicle, such as the front part, the mounted AU737 cooler, pantograph, and roof equipment. Accurately reproduces the delicate gradation of the yellow-green line color on the front and door.
For conversion, the antenna pedestal was added and the cooler was aligned with other E235 series. To :US, Asia , Australia, Canada.
