Heat-related expansion places a lot of stress on the ties, ballasts, and rail anchors that keep the tracks fixed to the ground. Eventually, the tracks will buckle under the force. These are called sun kinks. It makes the tracks look like spaghetti.

Rail weights up to 90# per yard and with standard old lengths of 33-39 feet can be bent simply by spiking one end and slowly working in the other end to gauge. This works on curves as sharp as 16-18 degrees with this weight rail.
For example, well-built and maintained ballasted track might not buckle until it registers an increase above the neutral temperature of 50 F to 70 F, and the same track might not pull apart until it experiences a decrease below neutral temperature of 105 F to 130 F, emphasizing the need to correctly set the desired ...
About 1,000 derailments occur every year across the United States, according to the Federal Railroad Administration (FRA). In 2022, there were 1,044 instances of trains coming off their tracks. Broken or defective railroads are one of the most common causes of derailments, according to the FRA.
Fact #2: Railroad Tracks Are Private PropertyWalking on train tracks may seem like fun, but it's actually very dangerous, not to mention illegal. All train tracks are private property, so pedestrians should never walk on or near them.
The outer rail is raised to tilt the train to the inside of the curve - this provides roll-over protection and at cruise speeds gravity helps keep the train more or less centered in the track. The wheels are tapered and 'steer' the bogies away from the rails, so on a curve the train is 'steered' around the bend.
Generally laid perpendicular to the rails, ties transfer loads to the track ballast and subgrade, hold the rails upright and keep them spaced to the correct gauge. Wooden ties are used on many traditional railways.
When properly maintained by a Midwest railroad contractor, a modern running track has the potential to last for almost 30 years after its construction. It may be difficult to recognize the signs of deterioration in rails because they appear to last an entire lifetime.
The era of the freight train-hopping, job-seeking hobo faded into obscurity in the years following the Second World War. Many hobos from this era have since “caught the westbound,” or died. A small number of so-called hobos still hop freight trains today.
There are many reasons why Americans don't ride the rails as often as their European cousins. Most obviously, America is bigger than most European countries. Outside the northeast corridor, the central Texas megalopolis, California and the eastern Midwest, density is sometimes too low to support intercity train travel.
A comprehensive list and map of them can be found on abandonedrails.com. They claim there are 1,755 Abandonments. One can sort by state and see various pieces of information about them.
The longest regularly scheduled train in North America is Via Rail Canada's Canadian between Toronto and Vancouver, a distance of 2,775 miles (4,466 kilometers). The longest train in the USA is Amtrak's Texas Eagle between Chicago and Los Angeles via San Antonio, a distance of 2,728 miles (4,390 kilometers).
According to Wikipedia there are 149,910 kilometers of rail track in the United States (although many other sources say it is much larger at 226,000 kilometers or 140,000 miles).
In hot weather, the overhead lines that provide power to the trains can expand and sag. To avoid damaging the lines, trains must travel more slowly. If the overhead lines are damaged, we have to cancel or divert train services until they are fixed. This causes delays.
