(1) "Late-at-night" means the time between 22:00 and 24:00, and it is the time-zone of the lowest rate of utillizing of trains in the whole day. (2) On the whole, the line-section of train-operation at the time of 'Late-at-night' (shorten into ′L′time from the following) is very few and one-sided. (3) From the point of times of the final-start and final-arrival of each line-section of our country, according to the time zone in the eight districts, the stations which have the final-start and the final-arrival occupy 4%, and in Kanto and Chubu, they occupy from 40% to 42%. The stations which the final start and the final-arrival end till 20:00, occupy 60% in Tohoku and in Hokkaido. (4) If we examine the final-start and final-arrival in the same station, we can see many of the end at 200:00 in Tohoku and Hokkaido while in Kanto end 24:00. (5) The frequency of starting of trains more than two times at ′L′time′, is 30% and the rate on the whole is 4%. By the way, the frequency of Tokyo Station is 42 time and that of Shibuya of Tokyo is 17 times. (6) In order to see how a train is operated at ′L′, I make out (M) as the average frequency of train. In the relation between (M) and the length of line-section, the increase of the line-section generally shows the decrease of (M). But if the scheduled-speed is 35km in one hour, (M) makes I. If this is considered to be a standard, Senseki, Minobu, and Kansai are higher than this standard, and Muroran Minami (between Oshamambe and Higashi Muroran) Hohi and Senzaki are lower than this standard. In the case of M I, and the length of line-section is than 70km., the double-operation is adopted in that line-section. This suggests that there are local cities distributed. (7) To observe the distribution of line-section at ′L′time′ even a main line is not completely connected. Tokaido Honsen is a connected line which is nearly perfect. The distribution of line-section at ′L′time′ in Tohoku Honsen is scattering, and it can be seen around local cities. (8) It is considered that position of ′L′time′ section is roughly divided into four headings : (1) the whole line-section Ex. Ito, (2) from the starting station, Ex. Hachinohe, (3) to the final-station, Ex. Tsugaru, (4) in the middle of line-section, Ex. Ban-etsuseisen. The line-section of the heading (2). is that the final-station divides the line-section two, and the indication from the starting station rapidly lowers at the final-arrival station forming a border. But it differs from the heading (1), and the area which the starting station dose not indicates is distributed in the line-sect ion. Ex., between Same and Kuji in Hachinoe Sen. In the line-section of the heading (3) is sectional and reaches from 7 to 70. The starting does not occur at ′L′time′ in this line-section. Therefore the distanse of operation which is long can be seen. But a train which starts at 8:00 and arrives at 23:00 is not supposed to have an indication which the starting station has towards the arrival station. It is supposed that the station indicates arrival station in the line-section of 50. But trains from the starting station do not occur at ′L′tim′, hence forth the relation between the starting station is considered to be wealer than tha heading (1), as Koriyama Aizu Wakamatsu in Banetsu Sen. In the line-section of the heading (3), the starting station and the arrival station have a less influence with each other like heading (3). But it differs from (3). and the area which the starting station and the arrival station do not indicate, exists.
