Note that while a small coin is not likely to have any effect on the train, larger objects, like a brick left on the track, can lead to derailment. Meanwhile, even smaller objects can damage the internal components of the train, such as its braking systems. Therefore, it is best not to put anything on the rails.

A derailment of a train can be caused by a collision with another object, an operational error (such as excessive speed through a curve), the mechanical failure of tracks (such as broken rails), or the mechanical failure of the wheels, among other causes.
A penny left on the tracks is too small to derail a train. Don't try this out, though, as many people have been killed in the attempt. Public domain image, source: U.S. Farm Security Administration.
A damaged railway tire was the cause of the Eschede train disaster, when a tire failed on a high-speed ICE train, causing it to derail and killing 101 people.
According to train accident statistics, broken or cracked rails and welds contribute to more than half of the train derailment accidents in the country. A traditional track structure consists of two pieces of track supported on transverse sleepers.
Placing big, tough stones on railway tracks is extremely dangerous and can have serious consequences. It is illegal and considered an act of vandalism or sabotage. Doing so can lead to severe damage to the train, derailment, or even endanger the lives of passengers and railroad workers.
There are about three train derailments per day. They usually aren't disasters The U.S. saw more than one thousand train derailments last year, but industry leaders say traveling by rail remains one of the safest methods of transportation.
The accidents are often minor and rarely lead to death or injury, though some have led to major environmental disasters. About 1,000 derailments occur every year across the United States, according to the Federal Railroad Administration (FRA).
Compared to other popular forms of travel, such as cars, ships, buses, and planes, trains are one of the safest forms of transportation in the United States.
Track Defects are the Most Common CauseTrack defects emerged as the leading cause of train derailments. The significance of continuous infrastructure maintenance and inspections cannot be overstated.
While modern trains won't litter the tracks with human excrement, the traditional method did just that. This is what was known as a hopper toilet. It could either be a simple hole in the floor (also known as a drop chute toilet) or a full-flush system.
Standing upon (or making bodily-contact with) both wheel-rails of a railroad line simultaneously would almost-certainly not result in a life-threatening (nor even mild) electrical-shock of any sort (they are grounded and almost never carry any more than a few stray, harmless volts of electricity, if any).
If you touched the live third rail and any one of the others, or to the ground, yes. It's not only at a high voltage, but it's also DC which has the effect on your muscles of clamping on so you can't move. At least AC is at zero Volts every so often... But between the two normal rails probably not.
#1 Sri Lanka Tsunami Train WreckThe train, dubbed the Queen of the Sea, was destroyed by the Indian Ocean tsunami on December 26, 2004, in what is now considered the world's deadliest rail tragedy.
A halted train isn't immune to derailments, however. To guard against derailments, JR East has installed L-shaped metal parts on its train cars as a countermeasure. The parts are designed to hook the cars on the rails, thus preventing them from colliding with side walls.
