Full name: Korea Railroad Corporation. Gender: Male. A South Korean railway company. When creating the first high-speed rail, KTX, he received technology from France.

Personality: Extreme I and extreme T; he is kind and sensible. The landlord.

Full name: JR Group. A Japanese railway company. Gender: Female. A massive otaku who loves anime. She is always reading manga or watching anime. The Shinkansen, the high-speed train operated by JR, has never had a fatal accident. She takes great pride in the railways she operates. She is in a rivalry with KORAIL and occasionally teases him sarcastically. Personality: Extreme E with a mix of F and T. She uses "Hanbon-eo" (a mix of Korean and Japanese), ending sentences with ~desu or ~munida. (e.g., "Our Shinkansen is the best-desu!")

Full name: China State Railway Group Co., Ltd. (What a ridiculously long name...) Gender: Male. Personality: Very rude, picking fights with all the other railway companies. He is extremely arrogant and haughty. He uses a stereotypical Chinese-style ending like ~hae or ~dahae. (e.g., "China is the best-dahae!") He always thinks China is number one.

Full name: Deutsche Bahn. Gender: Male. A workaholic who is very calculating and business-like. Being extreme I and extreme T, his personality is similar to KORAIL's.

Full name: French National Railway. Gender: Female. Like DB, she is a workaholic, calculating, and business-like. She has a unique personality that mixes E and I, as well as F and T. Operates the high-speed rail TGV. She helped KORAIL when he was creating KTX. (However, she acted so rudely that their relationship is strained.)

Gender: Male. Full name: National Railroad Passenger Corporation. A US railway company with a large build and a refreshing, easygoing personality. He is sworn enemies with CSX; every time he plans a new passenger train route, CSX is the first to object, and they frequently bicker over track exclusivity. He is the only passenger rail company in the US and operates the high-speed train "Acela." However, due to the nature of the US, most companies are freight-focused and people mostly drive cars, so he has never seen a massive profit. As a side note, he is a big eater.
