One of the most significant problems in automatic ticket examination is to check the validity of the route written on a ticket. This problem is due to the service regulation that a passenger with a season ticket can get on or off at any station en route as many times as he likes.The problem can be divided into three subproblems; (1) coding the railways network, (2) describing the route onto the ticket and (3) checking the validity of it. The item (1) and (2) are concerned with representing the route on the ticket with as little amount of information as possible, and the item (3) is concerned with realizing the judgement function of an apparatus as simply and as inexpensively as possible.We propose a method to examine the validity of the ticket by describing the route with line-sequence codes. Two kinds of tickets are treated with one mechanism. One is a season ticket and the other is an ordinary ticket for short distance passengers.Microprogramming technique is employed for the checking circuit of the apparatus. With the same algorithm, an automatic fare adjustment is possible.The distinctive features of the proposed method are(1) to cover the nationwide network, (2) to handle two kinds of tickets with one mechanism both in automatic ticket examination and in automatic fare adjustment, (3) to cope easily with alteration and(4) to be able to utilize the same machine at different stations.

The improvement of adhesion characteristics is important in electric motor coach. We have already proposed the anti-slip/skid re-adhesion control system based on disturbance observer and sensor-less vector control. The effectiveness of the proposed method has been confirmed by the experiment and the numerical simulation using the tested bogie system of electric motor coach.Then, we apply the proposed method to the actual electric multiple units, which is Series 205-5000. In the experimental results of Series 205-5000, this paper discusses that the proposed anti-slip/skid re-adhesion control system has the desired driving wheel torque response. Moreover, this paper proposes the evaluation method of re-adhesion control test results.

We must switch from trucking to trains or ships for freight transportation in view of aggravating environ-ment destruction, depletion of fossil energy resources, and shortage of young manpower.High power electric locomotives have been developed and are contributing an increased freight transporting capacity. But we have to restrict their power output because of voltage drop and shortage of capacity on account of long interval of traction substations. We have studied an adaptive output power control system of them to exploit their full ability with computer simulation. We propose a new method of calculating the difference between the voltage of contact wire of locomotives and its limit, and the resistance of feeding system with the position of the locomotive and traction substation, and calculating the current to be increased within the limit. Otherwise we propose to reduce output power of locomotives according to the difference between voltage of contact wire and its limit. We show that high power locomotives can be worked within the voltage limit and the standard train running time can be maintained by computer simulation proposed in the above. Thus we can introduce the high power locomotives without any large investment to expand the existing substation and can work them to the limit of their capacity.

In electric motor coaches, when the adhesion force coefficient between rail and driving wheel decreases suddenly, the electric motor coach has slip phenomena. We have already proposed the anti-slip control system based on ordinary disturbance observer. In order to realize the more stable anti-slip readhesion control in case of large variation of adhesion force coefficient, this paper proposes a new anti-slip readhesion control based on first order disturbance observer and new torque function. In the numerical simulation results in this paper, the proposed anti-slip readhesion control well regulates the driving wheel torque of electric motor coach stably.
