I find the railroads from other parts of the world to be fascinating, Bill. I've ridden the rails in UK back when BR was dismembering the system in the mid 1980s.
When it comes to snow, to bring this back on topic, the railroads have quite a dangerous battle to fight no matter where in the world.
Here are some photos from New England of the railroads fighting the snow.

I can see how the weather can affect electric operations.
In the Boston area, the transit system, outside of the commuter rail, can come to a grinding halt during a snowstorm particularly when there's lots of ice build-up on the tracks.
The Orange and Red lines of the MBTA (Mass. Bay Transit Authority)'s two subway lines, have some above ground operations. In these sections, ice has been an issue when it builds up on the third-rail, causing the system to shutdown. The other problem with the trains on the Orange line is ice and snow getting into the relays. This causes the power to cut out, and simply disabling the train in the middle of nowhere.
The Blue Line, which has both catenary and third rail suffers from frozen pantographs. When the trains exit the tunnel near the Airport station, they raise their pantographs for the final leg to Wonderland station. The pantographs end up freezing down flat or up, causing the rail line to suffer from major delays particularly during rush hour.
The Green Line, trolley (tram, LRV) lines, have issues with frozen road crossings, switches, and the signal system.
When it comes to the commuter rail operations, which are not immune either from bad weather, there are signal problems. Two years ago, when we had the major ice storm, the commuter operations were halted. After the power was restored, there was still an issue with overhanging branches, and power outages with signals. The lines therefore were operated manually, which caused major delays. Last year there was a flooding issue, which put major sections of the Fitchburg line out of commission while the line was repaired.
As far as municipalities go, I think they're the same worldwide. Every year the city allocates a large sum of money to cover snow removal. We'll get our first storm soon. There will probably be a inch (2.5 cm) of snow. The plows will be out, scraping, salting, sanding and going all night like this is the biggest and worst storm of the century! Later on when there really is a big storm, no one will be out and the roads will be impassable. Why? Because the budget for snow removal was blown on the first nothing storm, so now we're stuck with a mess for the rest of the season.
