Huawei, a networking and telecommunications services company, has partnered with Alstom on the deployment of the world’s first live pilot test of 4G LTE data service integrated into a rail signaling system. Alstom integrated LTE 4G in its signaling system solution, which consists of Communications-based Train Control, and Passenger Information Systems. The pilot test was carried out on metro lines near the Valencinnes area in France in late June. Alstom and Huawei evaluated laboratory and static testing on trains, dynamic tests on metro tracks, and the test of LTE multi-services capabilities during the pilot. Huawei is a Chinese based multinational networking and telecommunications company. For more information, go to

Kelso Technologies Inc. obtained approval from the Association of American Railroads to begin commercial field trial testing on the company’s new Vacuum Relief Valve. The low-pressure device is specifically designed to protect tank cars from the effect of an excessive vacuum preventing the implosion of the tank car. The patent-pending valve design is a result of customer demand for a better performing product due to the failure rate of products currently in use. The device meets the new DOT-117 tank car specifications to be implemented later this year. Kelso is a railway equipment supplier that designs, produces and sells proprietary tank car service equipment. For more information, go to

Saft has been awarded a contract from Bombardier Sifang Transportation Ltd., a Chinese manufacturer of railroad passenger cars, for the installation of 100 MRX Fully Integrated Onboard Battery Systems for 20 new generation Project 807 Electric Multiple Unit.

The batteries will be installed on passenger cars for the China Railway Corp. and their high-speed rail lines. The first prototype train using the Saft battery type is in operation on the Qinhuangado-Shenyang line. Once additional testing is completed, the new type-807 train sets will be deployed on high-speed services across China. For more information, go to
