To help the wheels stay on the track their shape is usually slightly conical. This means that the inside of the wheel has a larger circumference than the outside of the wheel. (They also have a flange, or raised edge, on the inner side to prevent the train from falling off the tracks.)
Contact wire is generally built in zig-zag to reduce the wear on pantograph slide. When the train is running at a high speed, the contact wire has to face the extreme working environment such as vibration shock, temperature difference, environmental corrosion, mechanical friction, and arc ablation [48].
Do trains drop waste on the tracks? Not anymore. In the US until the 1960's, some toilets emptied directly onto the tracks. A sign was posted over the toilet reminding passengers not to flush while the train was on the station.

Passenger accidentsTrams coming to a sudden stop may cause injuries to passengers on board. Passengers may also slip, trip or fall on the tram or the tram platform. Blind passengers may particularly be at risk of falling off a tram or getting injured by closing doors.
