Parallel Systems Wins $4.4MM DOE Grant

Culver City, Calif.-based Parallel Systems has been awarded a $4.4 million U.S. Department of Energy (DOE) grant to test its autonomous, battery-electric-powered railcar technology. DOE is distributing a total of $175 million to 68 projects through the Advanced Research Projects Agency-Energy (ARPA-E).

The Rail Escort Vehicle (pictured) was designed in accordance with Association of American Railroads Standard S-2043 for trains used to transport spent nuclear fuel and high-level radioactive waste.

‘No Ordinary Caboose’

The U.S. Navy and the U.S. Department of Energy (DOE) have developed a new Rail Escort Vehicle to transport security personnel during the shipment of spent nuclear fuel and high-level radioactive waste; it is on its way to the Transportation Technology Center, Inc., (TTCI) for the final phase of testing.

Laboratory Testing of Reconditioned Bearings

TTCI R&D, RAILWAY AGE NOVEMBER 2021 ISSUE: Roller bearing reconditioning is a common practice in the railroad industry, with 90% of the bearings in revenue service having been through the reconditioning process. Transportation Technology Center, Inc. (TTCI) is collecting test data on the performance and service life of bearings following reconditioning repairs. The testing for this research project consisted of two phases.
