The Kosei line runs from Kyoto up the West side of Lake Biwa and tends to feature this older, more basic style of train, even though some of them look brand new. They are noisy and bumpy. Perhaps they're cheaper and the lower passenger numbers on this route don't justify the expense of the modern style trains.
