Track
Broken trackis the number one most common cause of train derailments. Broken track is a catch all I’m using to describe a few different ways track can ‘break’: 1. The distance between the two rails changes; 2. Twists in the rail - when the rail transitions into a curve (think about the force you feel when you start turning in a car at speed). 3. Cracks develop in the rail, it can even split into two pieces;
Trains
Trains can derail themselves due mostly to broken axles and broken wheels. How do axles and wheels break? Heat. If a rotating part gets stuck, or brushes against a part in a way it shouldn’t, it will get hot. As the rest of the heavy train forces this part along, it will get very hot. If it gets too hot it will break. A hot axle or hot wheel can break down, particularly if there are already cracks or other problems in the metal. Once that happens, the wheels can derail and take the train with...
Weather
In the 4 year study period, weather caused 2 derailments. Trains work great over long flat stretches of land; unfortunately so do floods. In one case, water flooded through the tracks after heavy rain and washed away the rocks and dirt (ballast) holding the tracks in place. Without ballast holding the tracks in place, the next train to go over those tracks fell off, even at its slow cautionary speed. Imagine how tall a shipping container is. There are some train carriages which are taller. Al...
Fixing broken rail is the job of the Permanent Way Engineer. Permanent Way Engineersinspect track to try to find evidence of these problems occurring, and fix it when they can. Inspecting the track might involve driving a special vehicle over the top analysing the track for problems, or it might be as simple as walking along and seeing if you can s...
I looked at 4 years of reports from a jurisdiction that requires reporting of derailments. This record included 22 derailments, or approximately 5.5 derailments per yearover the tens of thousands of train travelled kilometres in the country. No one was seriously injured in this time, no one died. There was however costly damage to infrastructure th...

In rail transport, a derailment is a type of train wreck that occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard.
Derailment of rolling stock is defined as a wheel or set of wheels leaving their due place from the rail top surface. A derailment may be minor or major in nature i.e. just
