How does a train pull so much weight?

The locomotive connects the bogies well above the center line of the loco wheel. When the loco pulls the frictional force (rolling) times the bogies total weight makes the rear wheels of loco to exert more vertical force (due to moment arm) and this adds up to the loco dead weight.

The heavier a locomotive is, the better the coefficient of adhesion, and the better the locomotive can transmit power to the rails without wheel slippage.

What happens to toilet waste on trains? While aeroplanes dumping waste onto the ground is an urban myth, trains, on the other hand, are a different story. While modern trains won't litter the tracks with human excrement, the traditional method did just that. This is what was known as a hopper toilet.

Only freight trains have locomotives on both sides and sometimes in the middle also. The reason for that is traction to push or pull heavy loads.

A train engine requires about a hundred litres of fuel to get it started. So it wouldn't be economical if the engine is stopped and started frequently. This apart, if the engine is stopped, the moving parts' lubrication will also come to a halt.

As with internal combustion engines that are used in more traditional ways, engines used as power generators in diesel electric trains are also considerably more efficient thanks to the use of turbochargers.

The horn alerts people that a train is approaching a railroad crossing. It can also be used to warn animals or trespassers in our right-of-way along a section of track. Many people don't realize that federal and state regulations require us to sound the horn whenever we approach any crossing.

A story of US transportation Highways (as well as aviation) became the focus of infrastructure spending, at the expense of rail. This trend has continued, and not the least because highways require continuous maintenance, while the US's growing population demands more lanes and roads to relieve congestion.
