development of fixing panel method into railway and fixing bracket
We have completed creating trial models such as stainless hooks, insulating wire, fixing brackets. Mounting instruction is to make a hole on the frame of solar panel, pass a wire through, and decided on fixed style using turn buckle.
Also we have managed to fix the area around the hole.
Scheduled trials
April 2014 Tokyu Railroad
June 2014 JR Technical Research Institute (Kunitachi Testing Course)
July 2014 Local Line (under negotiation)
August 2014 Local Line (negotiating to do an experiment on track during maintenance)

Wind endurance Test
This research is for solar panels that will be set in between the railways.We seek for the peak of wind factor from wind tunnel experiment.
Results of the research are as below:
1. This research was done on a flat area, without any surroundings, assuming no train to pass over.
2. Samples made for this experiment was in scale reduction of 1/10, we have created railways, railway sleeper, solar panels and cushioning materials 20m in length.
3. There are 2 cases, case 1 is to place it in the center of solar panels lined up one after another, and case 2 is to place it on the edge of it.
4. The peak of wind factor, in any case, goes up when it gets blown up. With the panels placed in the center, it was -0.48, panels placed on the edge, it was -0.46.
5. We have done calculation on wind load by utilizing the result of peak wind factor for building. Wind load for designed panel, sized is 240N when placed in the center, and 229N when placed on the edge.

Vibration Test at the time of train running
Test planned at Railway Technical Research Institute (National Testing Course) from June 19th to 21st. We will place 3 solar panels in between the rail ways, set measuring tool on each panel, and have a train run at the speed of 40km/hour. We will measure near the joint of the rail, and a part from it, and calculate the condition when high-speed train went over it. We will utilize the result for stress calculation for wire and panel and also to choose the size and the type of cushion materials. Additionally, we will have removing and installing test during this time.

Research on objections preventing from installation
We have feed backs from Kominato electric Railroad, Kashima Rinkai Railroad, Amaki Railroad, Tosa Kuroshio Railroad, Hojo electric Railroad, Ichibata Railroad. Amaki Railroad, Tosa Kuroshio Railroad, and Ichibata Railrord are very positive about installation, they will consider depending on our finance.
Track Maintenance is manageable, replacement of railroad tie will be once a year, ballast will be replaced partially, there should not be any issue with the course as there are over 10km of straight course. Finance is the only issue. On the other hand Kashima Rinkai Railroad has only 8 members for track maintenance who are currently fully working during day time, they don’t have enough manpower for installation. Kominato Railroad is interested in panels,however, they need to find a solution for track maintenance.

Possibilities with Storage battery trains
It is possible to run the train with electricity converted from solar panel in between the rails. JR is investigating possibilities with Storage battery train system which needs to convert AC (alternating current) into DC (direct current) and store. However, it seems like the AC stored from the panel may be directly utilized to run the train, we will communicate closely with Researcher.
