It's rare that a train might cancel a trip altogether due to weather, but it does happen. In winter, ensure that you keep your eye on the weather in order to keep surprises and unknowns at bay.

Ice can be the worst problem for a train to have to deal with. With icy wheels and train tracks, trains may not be able to stop properly at stations and red signals making it very dangerous.
Frozen Switches/Switch FailureSwitches allow trains to move between different sets of tracks and are placed at numerous locations across the system. Snow and ice build-up can block and freeze a switch and prevent it from working.
Ice coating the electrified rail (in areas with an electrified third rail) stops power reaching trains. Rails freezing together means signals stay red and trains stop. Heavy snow can make branches break off trees, damaging overhead wires and blocking the track.
Compacted snow and ice on tracks can cause derailments. Flangeways at road crossings should have clean grooves to reduce the potential for train wheels to derail.
The answer is yes trains have derailed while plowing through snow. This is a major problem trains have during winter. Snow accumulations can easily derail a train or worse bury or derail the train in an avalanche. Where trains travel in areas of heavy snow such as Donner Pass over the Sierra Nevada Range in California.
In the US, standard stress free temperatures vary from 35 to 43 °C (90 to 110 °F). Despite stressing the CWR before installation, a rail may still reach its Critical Rail Temperature (CRT). This is the temperature of the rail above which buckling may occur.
Tracks are affected by extreme cold in two ways. In some cases the tracks experience what's called “pull-aparts.” This kind of rail defect occurs when two rails separate at their connection. The extreme cold shrinks the metal and the rails literally pull apart from each other, Metra said in a recent Instagram post.
The two methods to minimize ice build up are through the use of direct heating and spraying water. The first, and more common method is to directly heat the rails. Electrical equipment can just add heating coils to melt snow and ice in the immediate area.
Mainline locomotives are equipped with snow plows that remain in place year-round. When there is too much snow for the locomotive to handle, railroads use specialized on-track machinery to clear the tracks.
You will often find propane heaters that will keep the switches clear of snow and ice on mainline tracks in Canada and the Northern US. The tracks otherwise are not heated and in severe cold have significant speed reductions due to possible brittleness and contrction.
Check your train company's website to find out if they offer Delay Repay (they might call it 'delay compensation'. You're legally entitled to compensation of: 50% of your ticket price if you get to your destination between 30 minutes and an hour late. a full refund if you arrive more than 1 hour late.
Switchers idle for several reasons. Some of the most common reasons include ensuring the engine is ready for immediate use, avoiding difficult start-ups due to a cold engine or a weak battery, and preventing freezing inside the engine. Locomotive engines do not use antifreeze.
If you're delayed and arrive at your destination more than half an hour late, you'll usually be able to get some money back. Some train companies will also give you compensation if your train is more than 15 minutes late. You need to keep your train tickets to get a refund.
