| Here we come to San Bernardino County Transportation Authority (SBCTA)! The vehicle must be pollution-free, work in high heat (of up to 49 degrees Celsius / 120 degrees Fahrenheit) and drive for a day without refuelling. There the train will cover 14.5 kilometre / 9 miles route up to 16 times a day without having to refuel. So far, diesel-electric trains have been running there. |
