Trains can derail because they are going to fast around a corner, or it could hit some sort of obstacle, which would cause it to derail. A train is not set up like a steel roller coaster where there are wheels on the top, the side and the bottom. On a train there are only wheel on the top with a lip on the inside edge which holds them on. Mmechanical failures such as a hot box (hot journal) that goes undetected long enough, broken wheels or problems with track gauge, broken rail, and washouts among many other problems can lead to a derailment Anytime there is an emergency application of the brakes there is a risk of derailment. Gapped, run through, or misaligned switches can cause derailments.

How often do trains derail?

Trains do not derail often in the US, and the overwhelming majority of train derailments are by freight trains, not passenger trains. Today, rails are much higher quality in years past and are checked regularly such that the most major cause for derailments by a train is now quite rare in the US, typically occurring now due to extreme hot or cold weather instead. But rail cars derail. Prior to becoming a train, railroad cars and locomotives derail very often in yards and on private company sidings. These cars derail very often and at extremely low speed and rarely have any damage or problems. On a company siding, the company must maintain the tracks, not the railroad, so maintenance on private property can be 1 cause. Within a yard, because a very low speed derailment is a minor nuisance with no damage, there may be lightly used tracks that simply aren't maintained at the same level as others. Then you have the rail cars, owned by many different companies and not under the control of the railroad moving them in the yard, which may have mechnical problems that result in derailment. (That's why these are inspected as they make up a train in the yard, to prevent this on a main track) On any given day, there likely are a dozen or more car derailments in the US, but not train derailments.


How are trains safer and how are they faster?

They have dedicated railroad tracks which makes it difficult for someone to derail by driving it into a random tree or object as would an automobile on a road. That same principle of dedicated railroad tracks ensures that trains don't have to cut each other on lanes as there's rules and signals installed to prevent conflicts, therefore minimizing traffic.
