Heavier locomotives if fitted with a snowplough can cope with a foot or so of snow. These will sometimes be used on high speed and commuter lines to clear heavier snow that has built up overnight.

It will depend on the initial momentum of the train (speed and/or weight) and what type of snow. Powder, like skiers love, will basically blow away. The opposite type is a hardpacked drift in a shallow cutting. The latter has been known to to derail a train, which then stops really quickly.
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.
Light rain won't cancel your trip, but it could lead to delays. When it rains, the tracks become slippery and the train must slow down in order to accommodate for the extra time the train will need to brake.
Like driving on icy roads, acceleration and braking are much harder on icy tracks. In fact, it's even more difficult on the railway because the train wheels and rail are both made of steel. This means wheels can slip because it's harder to get the friction needed to accelerate or brake.
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.
This abuse, however, comes at a price when he accidentally kills Robin Ward by running through her. Vought covers the incident up, however, at a press conference by claiming that A-Train was attending to a bank robbery.
If a train is cancelled (and that's what's happened here) you're entitled to take the next train that matches any restrictions on your ticket. So if your ticket is routed via a certain place, you must go that way, or if it's only valid on a certain train company, you must use that companies services.
How much you can get for a cancellation. You're entitled to a full refund if your train was cancelled and you couldn't take the next train or decided not to travel. If you didn't use your ticket, you can get a refund without any fees - it doesn't matter what type of ticket you bought.
When the train stops, there is no force acting on the object (passenger), so he will remain in motion. This is why when suddenly the train stops, due to the law of inertia or Newton's first law of motion, the passengers are pushed forward.
In rail transport, a derailment occurs when a rail vehicle such as a train comes off its rails. Although many derailments are minor, all result in temporary disruption of the proper operation of the railway system and they are a potentially serious hazard.
One instance is where the railway track is at a slightly higher level than the road approaches on either side. A long vehicle such a s a low loader can become grounded on the “hump”. Another situation is where, at a level crossing, a driver mistakenly leaves the road and turns onto the tracks.
As the outside wheel's circumference becomes larger it is able to travel a greater distance even though it rotates at the same rate as the smaller inside wheel. The train successfully stays on the tracks! In this activity you will test for yourself how train wheel shapes impact their ability to stay on track.
