Why is one locomotive always backwards?

For the most part, it doesn't matter which way a modern locomotive faces, it works just fine either way. Typically though, the main reason some locomotives will be facing backwards is because turning trains is not always easy. In the past, you would need a wye, loop, or turntable to turn a train/locomotive around.

One of the primary reasons railroads use distributed power is to increase the pulling power of the trains as the length and weight also increases. By placing additional locomotives in the middle or at the end, the overall pulling power of the multiple locomotives increases, moving the train efficiently and effectively.

Other than making the horn sound different, chimes are turned around for safety reasons. Most locomotives make occasional trips backwards, so rearward-facing chimes are a necessity. Until radios became standard, rear-facing horns also helped train crews hear horn signals from the front of the train.

UK diesel and electric locomotives are usually fitted with two-tone horns, sounded sequentially to distinguish them from the horns used on road vehicles, the tones being described as either 'high' or 'low'. In the past, both tones were routinely used.

Under the Train Horn Rule (49 CFR Part 222, issued on August 17, 2006), locomotive engineers must begin to sound train horns at least 15 seconds, and no more than 20 seconds, in advance of all public grade crossings.

Anyway, the reason for using two locomotives is pretty simple. Twice the number of locomotives means twice the power. This extra power boost is used for especially heavy loads or for trains going up steep grades.

In our world, a catenary is a system of overhead wires used to supply electricity to a locomotive, streetcar, or light rail vehicle which is equipped with a pantograph.

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.

Yes, locomotive engines typically have a toilet, also known as a lavatory or restroom, for the use of the crew members who operate the train.

In railroad terminology, double heading indicates the use of two locomotives at the front of a train, each operated individually by its own crew.

Train operators and conductors play distinct and important roles: Operators drive the train, while conductors make announcements, stick their heads out of the cab to give the operator the all clear, open and close the train doors, and interact with passengers directly.

Conductors and engineers sleep at home or at a hotel at their away terminal. The operating crew of a train in the US can only be on duty for 12 hours and then must be relieved.

When they aren't being used they are parked somewhere because it's more economical to store them until they're needed rather than scrap them.

Eight notches allowed reasonable control throughout the range of zero to everything. The concept also allowed MUing locomotives as only a few wires, energized in various combinations, could control the unmanned locomotives through the notches.

As a train slows down on steep grades and tight curves, or approaches a signal light or stopping destination, sanding assists in preventing the wheels from sliding as the braking systems are applied. Sanding has been used to increase friction and improve traction since the very inception of railroad transport.

One long whistle (three to 10 seconds) means the train is approaching a station.

The reason that trains honk their horns so much at night is because it's dark and the trains aren't so easy to see. Even though the lights are on, we sometimes can't see them coming, especially around the many blind curves near or ahead of the train station.

Anyway, don't blame the engineer: They're required to blow that horn. The regulation in question is called the Final Rule on the Use of Locomotive Horns—a name that strongly implies they've had just about enough of your bitching—and it requires four blasts 15 to 20 seconds before every crossing.
