a river flowing through a lush green forest

We accidentally hopped into Rapid train. Supposed to go 3 stops but went further than we supposed to. Train was going in high speed, went into mountain tunnel, pitch black. But suddenly light struck us. First i couldn't believe my eyes. Mountians were sky high with full of clouds and rivers. Never seen such beauty. That part only lasted 1 second. Then again tunnel. couple of seconds and again this view...
