What is Transfer Transport?

If you carry out transfer transportation due to an accident or other reason, if you have a commuter pass, ticket, coupon, etc. for the troubled section in advance, you can use the section by other specified routes. (Using the IC card with the remaining charge, and the special ride card for the elderly (Keiro Pass), special welfare ticket (Welfare Pass), and special ticket are not eligible for transfer transportation.)
