Yes, trains should have stricter safety regulations. Many people have died on or near trains or have been wounded on or near them. They are a mostly safe environment, but they can always be safer. More railings and more security personnel couldn't hurt. They might save the lives of people.
Yes, trains should have stricter safety regulations. Trains are very large and accidents that involve trains generally result in fatalities. Because of the danger that they present if they are not operated properly, trains should have stricter safety regulations imposed upon them. Some more regulation is needed in the industry.
Trains are much safer than cars or trucks in terms of vehicle miles travelled. A train derailment is simply a spectacular and negative story that produces great footage, so they get a lot of publicity. Over-regulating the industry would just put more cars and trucks on the road, forcing people into a more dangerous mode of travel.
Trains already have enough regulations. At this point, it would be impossible to make any more rules for the trains and the people who run them to follow. A better idea would be for the vehicle driver or pedestrian to be sure to follow safety rules from their side of the tracks. People need to stay off train tracks all the time unless they are properly crossing them in a vehicle.
