Ⅳ. R&D Results
1. Design & manufacture of a 3rd rail type power collector suitable for the structure of steel-wheeled light rail vehicles
A. Development suitable for the technical regulation (steel-wheeled light rail vehicles) and standards (KS C IEC 60494-2)
Technical regulation for urban rail vehicle (steel-wheeled light rail, MOLIT public notice 2017-595) and International Standard (KS C IEC 60494-2) were considered as criteria for the design conformity & suitability of the 3^rd rail type power collector developed in this project. In the process of manufacturing and performance verification of the 3^rd rail type power collector, the design criteria, manufacturing specifications, and verification method were proposed.

B. Examination of infringements possibility on European patents (patent lawyer)
For the final design of the 3^rd rail type power collector, it was examined whether the developed power collector might infringe patents. Five related patents were selected based on the results of the patents examination results conducted in 2017. Finally, two patents (DE10-2016-118735, EP 1586480) were investigatedexcept 4 patents such as expiration of term and termination of rights. The patentlawyer appointed by KRRI issued examination report that the developed productwas not within the scope of the foreign patent right.

C. Completed the maintenance manual for 3^rd rail type power collector
The maintenance manual was proposed on the basis of design documents and the test procedures for the 3^rd rail type power collector developed in this research. The maintenance manual provides countermeasure information in failures, technical information on maintenance standards and procedures which will be used as reference materials for future commercialization.

D. Technology Readiness Level (TRL) 6
The 6th stage of TRL (Technology Readiness Level) has been accomplished by obtaining the test report (general) issued by the accredited testing institute (SGS)for 14 tests and inspections.

2. Verification testing (3rd party verification)
A. test procedures development
On the basis of technical regulation for urban rail vehicle (steel-wheeled light rail, MOLIT public notice 2017-595) and International Standard (KS C IEC 60494-2), test procedures was proposed to carry out performance verification(manufacturing, inspection, testing, etc). Inspection and testing were performed and evaluated on the test procedures (criteria). Self-preliminary testing and inspection, testing and inspection by accredited testing institute were completed by using the testing jig and equipment including wear measuring of power collecting shoe manufactured in the 1^st year (2017) ^[1].

B. Design & manufacturing specifications for the technical regulation for urban rail vehicle (steel-wheeled light rail) and international standard
Technical standards and specifications were surveyed and analyzed, the technical regulation for urban rail vehicle (steel-wheeled light rail, MOLIT public notice 2017-595) and International Standard (KS C IEC 60494-2), which were applied to the design and testing for the 3^rd rail type power collector.

C. Self-preliminary inspection for 1^st and 2^nd prototypes
The 2^nd prototypes (7 sets) were manufactured modifying the shortcomings found in the preliminary tests (and inspections) for the 1^st prototypes, and considering the compatibility with the existing products. Based on the confirmed specifications and test procedures, self-preliminary tests for the 2^nd prototype were carried out, which was used as reference for the accredited testing.

D. Testing report (14 tests) for final (2^nd) prototype issued by accredited testing institute(general)
After preliminary consultation with accredited testing institute (SGS) for test items, standards and schedule, testing report (general) for 14 tests was issued which can prove the reliability of the final prototype. It will be used as a reference for commercialization of the developed products in future.

3. Development of power collecting shoe
A. Mechanical performance test of power collecting shoe (KS D 4302)
After developing the power collecting shoe (spheroidal graphite cast iron-based material, GCD 600-3) suitable for the steel-wheeled light rail vehicles, the mechanical performance test was carried out according to KS D 4302 which results in test report issued by accredited testing institute. The power collecting shoe developed in this research meets KS D 4302 (SPS-KFCA-D4302-5016, Korea Coal Industry Cooperative Standard), which is equivalent to the mechanical performance with foreign product.

B. Wearing test of power collecting shoe
The testing report (general) for wearing of the power collecting shoe was issued by the accredited testing institute (SGS) for the purpose of comparing with the foreign products and evaluating the reliability. The wearing test was carried outthrough an accredited testing institute 2 times at the testing equipment which was constructed to rotate the original plate of the same material as the 3^rd rail(conductor rail) at the average train speed.
