      我是快乐而沉静的雨。我从天空中飘落，伴着我欢快的足音，花草荡yàng(    )出陶醉的笑意；我和着自然清新的空气，将温柔的胸pú(    )轻轻地贴近土地，在泥土中消róng(    )。“我来了，我来了就不再回去。” 我用灵动的声音，奇异的形体和清透的心灵向你诉说，不知道你是否读懂了我——雨的心曲？

    It is not easy getting the attention of tourists away from the well-known white sandy beaches of Byron Bay. But in this relying Australian surf town, a solar (太阳能的)-powered train might just do a good job.

    Opening to the public in December 2017 along a 1.9-mile-long stretch (一段) of track that sat abandoned for more than a decade, the Byron Bay Rail Company has breathed new life into a pair of disused railcars dating back to the 1940s. They're now used to transport passengers between Byron Bay's central business district and the North Beach area. After remaining in service as part of a regional passenger rail network until the early 1990s, the aging railcars were out of service and sat uncared for — almost destroyed by time and unpleasant Aussie climate — in a railyard for more than 20 years. You'd never know it by looking at these nearly 70-year-old workhorses today, though: they've been decorated, equipped, topped with custom-made photovoltaic panels (定制的光电池板) and rearranged to accommodate up to 100 seated beach goers.

    It's those train-top PV panels that truly set the Byron Bay Rail Company's flagship train apart from other heritage rail restoration projects.

    Drawing additional power from a 30-kilowatt solar array (阵列) located atop the train's storage building, the tain is said to be the first in the world to be completely powered by the sun. Solar energy caught by the 6.5-kilowatt train-top solar panels is stored directly in an onboard battery system that powers motors, lighting and the like. When stopped at its home platform, the train pushes into chargers for quick battery top-offs with electricity produced by the storage building's rooftop solar array. The 77 kilowatt-hour battery can hold enough juice for 12 to 15 runs on a single charge. During long periods of cloudiness when the solar arrays don't get enough sun, the train uses the main electric network, supply using renewable energy sold by community-based service Enova Energy.

    The Byron Bay Rail Company's first-in-the-world folly solar-powered train is a good example of historic rail preservation with a 21^st century development. Operating as a not-for-profit company, the Byron Bay Rail Company also expected the AU$4 million line to be a way to relieve traffic jam between downtown Byron Bay and the rapidly growing North Beach area. Really, there's no bigger unpleasant thing than sitting in bad traffic for 40 minutes trying to get to the beach.
