Are there cameras in tunnels?

Video surveillance in tunnels For high-performance, safe transportation infrastructure. Seamless video surveillance is essential for the safety of particularly hazardous road and rail sections in tunnels. A winding road layout or different altitude profiles in the tunnel also influence camera installation.

Walking or playing on railroad property is trespassing. It is illegal, very dangerous and poses a serious safety and security risk.

Railroad tracks are private property, not public trails. It's illegal and dangerous to walk on or near tracks unless you're using a designated crossing.

The middle of the train is by far the safest for persons. The National Transportation Safety Board does not release comprehensive data on where victims were sitting during fatal train accidents, though some details are available in individual investigative reports.

What happens if you stand too close to a train? Air between person and the train moves with high velocity due to dragging effect and the air behind person is approximately still.

The parallel lines of the rails converge toward the horizon and fool our minds into thinking the train is farther away than it actually is. It is virtually impossible to accurately judge the speed of a train when these combinations of illusions are present.

Yes, but not during flight. Only in ground and after landing once in the gate. Actually, that's the rule for anyone who's not member of the cabin crew, not only kids. Exceptions to the rule exist, but they must have been certified prior to the flight.

Changes were made to cockpit security in order to make hijackings more difficult. The US Federal Aviation Administration recommends that doors be strong enough to withstand a grenade blast. Also, they are usually left locked for the duration of the flight.

Plane travel is safest, reports Ian Savage, of the Dept. of Economics & Transportation Center at Norwestern University, in the Huff Post Live video clip above. Trains are three times more dangerous than flying but safer than traveling by car (which is 40 times more risky than flying), according to Savage.
