Why does a train service have so many problems with frozen switches in the winter in Canada?

Question:
Go Transit and CN seem to have great difficulty with frozen switches during the winter in Canada. Don't understand why there are more problems in recent years. Canada hasn't turned colder than it has in the past. Winter is not a new phenonema. And trains are not new methods of transportation.

I agree, there are many problems with frozen, stuck, and snowed-in switches in the winter. It's just a fact of life on the railway.

Some winters are worse than others, and the type of weather, not just the temperature, has an effect. Wind levels, the type of snow that falls, the amount of ice that forms, and how much snow falls all play a part.

But, as someone else has mentioned, decreased manpower has a lot to do with it as well. It's no secret that railways in North America stand to lose a good chunk of their workforce due to retirement in the next several years. In many departments and locations, it's already started happening. Sometimes, it's just not possible to bring new employees online as fast as they're leaving.

On top of this, the modern railway is about as lean and efficient as it's ever been. This means doing less with more, and people are no exception. In a perfect world, the switches would be clean and thawed long before any trains needed to use them. But, such is not the case, hence why we all suffer the inevitable delays.

Industrial spur switches and yard track switches are another story. It takes people to keep these operating, which are no longer available as today's work force is too lean to meet the demands of the service.

In addition, extreme cold plays hell with the locks that accompany many of these switches, freezing them as well. But, that's why God invented fusees. Strike, apply heat, thaw lock, throw switch.

Do trains run every hour of the day the same frequency?


But, it is not just the switches that have problems with extreme cold. Much of today's main lines are composed of CWR (continuous welded rail), aka "ribbon rail." In extremely cold temperatures, there is no way for them to contract from the intense freeze and they literally "pull apart".
