While Europe reopens its frontiers, some trains have been running without stopping through foreign territory because of fears about infection. As a result, the trains were required to run nonstop on a 14-hour journey through European Union territory. They have now temporarily stopped altogether because Belarus, which they also passed through, has blocked the trains from its international lines. Other “corridor trains” remain in active service across Europe. The Europe by Rail team also point out that the UK is the starting point for one of the oddest “corridor trains”.
