This past Saturday in Bulgaria, a train carrying propane-butane(gas) derailed and exploded. 5 people were killed and 27 were injured. It destroyed about 50 nearby homes and buildings and other people had to evacuate. Its not sure what caused the crash. This incident is similar to the many other train crashes that have happened in America, which were due to speeding trains. I'm not sire if trains derailing is something that has been happening in the past, but it needs to be fixed in the future.

It seems that trains are very dangerous. I know they travel faster than cars which is why they are used but there must be more safety precautions taken to ensure more safety.
