Why do trains release steam?
Why do trains release steam? The steam generated in the boiler not only moves the locomotive, but is also used to operate other devices such as the whistle, the air compressor for the brakes, the pump for replenishing the water in the boiler and the passenger car heating system.

Do trains pollute the air?
These massive, track-mounted vehicles, which use a diesel generator to power electric motors and move rail cars carrying cargo or passengers, are major polluters, responsible for a growing share of the emissions that increase cancer risk, shorten lives and worsen smog across California.
Are trains worse for the environment than cars?
If we take an overall view of the transport sector, 71% of transportation related carbon emissions come from road users, whereas only 1.8% of emissions stem from rail travel. So in absolute terms, trains are responsible for a lot less emissions than cars.
Why do trains let out smoke?
The chimney (smokestack or stack in American and Canadian English) is the part of a steam locomotive through which smoke leaves the boiler. As well, steam locomotive exhaust systems typically vent cylinder steam exhaust through the chimney, to enhance the draught through the boiler.
What is the most polluting transport?
Finally, the plane is the most polluting means of transport and the one that generates the most greenhouse emissions.

Do trains dump their waste?
Modern trains recycle the waste water to use again for flushing.
Do steam trains have toilets?
Actually they did, except for the oldest. In the earliest years of steam railways trains did stop frequently, so all the facilities could be found at the station: Toilets, refreshments, sale of meals into the train. As the trains went on longer distances with fewer, shorter stops, they also had toilets installed.
Why are most steam trains black?
Black locomotives became common beginning in 1880, after coal burning engines made grime commonplace. Black was chosen because black locomotives didn't show all the dirt and grime that covered the locomotive during normal use.
Why is train smoke white?
The white smoke produced is typically pure steam, which is ideal for a steam locomotive since the engine is not wasting any energy. Brown smoke typically arises from the smokestack when poor-quality fuel is used. These fuels may be low-grade coal or even wood.
