Tra News is a trilingual (Chinese, English and Japanese) website on which you'll find some useful information if you're planning a trip around Taiwan and want to see what's happening. The short articles reflect Taiwanese rather than Western interests; there's a great deal about local delicacies and festivals which travelers who can't speak Chinese will find dull or bewildering. That said, the photos and details of numerous homestays (B&Bs) are useful when looking for somewhere to stay. Also, several establishments offer discount coupons through the website.
The letters "TRA" usually stand for Taiwan Railway Administration, which manages the island's conventional railroads. However, there seems to be no connection between this website and the railway agency - and there's no explanation on the site of what "Tra" stands for.
