Do trains stop running in cold weather?

Even when ice glazes the landscape or temperatures dip dangerously low, railroads run 24/7. Maintaining operations in the face of Old Man Winter isn't easy, but with careful planning, experienced and dedicated crews, and specialized equipment and technology, railroads keep serving customers winter after frosty winter.

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.

Like mentioned above, the rails aren't really affected by ice or snow. They are just chunks of metal. The biggest issue that rails face is the cold. Rails are restrained by rail anchors from expanding and contracting due to temperature changes.

Extreme cold causes steel rails to contract, which can result in a broken rail or 'pull apart' at rail joints.

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.

The main reason is because buses and trains are enclosed spaces, so the HVAC (heating, ventilation and air conditioning) system has to be kept on to ensure proper air circulation for everyone on board.

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.

Cold air decreases the velocity of sound, but doesn't affect it's intensity. However, the snow covered, windless environment would likely reduce the ambient noise environment, making it possible for more distant sounds to be heard than usual. Also, your valley location might magnify distance sounds in unexpected ways.

This means the trains must operate at much slower speeds to safely travel. Snow, freshly fallen or in days-old drifts, produces its own set of problems. It can get sucked into the engine, where it then melts and shorts out major components.

MORE DETAILS

Sometimes, the trains can stop in the middle because of technical or mechanical problems with locomotives or picking or dropping off the freight cars at the industrial tracks. They can also stop in the middle because they are waiting for the section ahead of them to get clear of a train occupying it.
