Does locomotive battery solar container technology require high technology

Because of their limited energy storage and long charging times, BELs by themselves may not be suitable for long-distance freight or passenger service until battery technology is more advanced. BELs can be used with overhead contact systems (OCS), hydrogen fuel cells, or existing. The primary benefit of battery-electric technology is that it can recapture and store braking energy, which is currently burned off as heat in today’s locomotives. Incorporating battery-electric into new locomotive designs (or multiple-locomotive consists) could reduce overall energy consumption. — SunTrain, a San Francisco company, is designing a method to transport power by rail, moving containerized batteries between solar and wind farms in Colorado to existing rail-served power plants in the Denver area. "This benefit is critical since fuel is one of the major operating costs for a railroad," he said. BELs use regenerative braking to recharge their batteries, especially traveling downhill.
