Can steam trains go backwards?
A steam engine will operate just as well in reverse as in going forward. Most tender engines, where the coal and water is carried in a carriage behind the locomotive, are designed to run forward but often run around their train and return the way they came with the train in tow behind the front of the engine.
On a steam locomotive, the reversing gear is used to control the direction of travel of the locomotive. It also adjusts the cutoff of the steam locomotive.
According to Jacobs, Union Pacific diesel locomotives are bi-directional, meaning they create just as much power traveling in reverse as they do traveling forward. Thus, the direction of the locomotive makes no difference to efficiency or safety.
The Class 52 steam locomotive can go backwards as fast as forwards (80km/h).
Trains have transmission gears, the answer is no. Locomotives are equipped either with Diesel-electric system or OHE in both cases electricity (in Diesel ooxo the Diesel engine is coupled to an alternator ) which in turn drives the traction motor.
Common reasons for a blocked crossing are waiting on the arrival of another train to pass or waiting to enter a rail yard. Occasionally, there are minor mechanical problems with locomotives or cars.
“Depending on the length of the train, as well as the length and number of tracks at a rail yard or customer facility, the train may have to move back and forth as it shoves cars into one track, backs out, and then moves forward to drop off or pick up cars on an adjacent track.”
Until the 1980s, laws in the United States and Canada required all freight trains to have a caboose and a full crew, for safety. Technology eventually advanced to a point where the railroads, in an effort to save money by reducing crew members, stated that cabooses were unnecessary.
Locomotives idle to be ready for immediate use, to keep fluids warm in cold weather, to maintain brake pipe pressure, and to provide crew comfort in heating and air conditioning the cab. These justifications come with a price, the biggest of which is fuel – an idling locomotive can burn upward to 3-5 gallons an hour.
The Short Answer. Trains have multiple engines to provide more power to pull the train. Each locomotive has a certain amount of pulling power (called “tractive effort”), which is related to how many horsepower the diesel engine in the locomotive has.
How does a steam locomotive reverse direction?
The left pedal, when fully released, allows the engine to move the car forward as the throttle is opened to apply steam to the engine. When the left pedal is fully pressed and held to the floor while the throttle is opened to send steam to the engine, the engine moves the car backwards.
All the commuter, metro & modern electric trains are a great example of DP systems where motors are located on both the ends as well as at the centre of trains. Extra power and locomotives are needed generally for freight trains due to heavy load and seldom for passenger trains.
But, since there will still be unexploited pressure in the cylinder at the end of the stroke, this is achieved at the expense of engine efficiency. In this situation the steam will still have considerable pressure remaining when it is exhausted resulting in the characteristic “chuff chuff” sound of a steam engine.
By placing DPUs throughout the train rather than just at the rear—thus distributing power more evenly—railroads were able to enhance a train's carrying capacity. Computers in both the lead unit and remote units also allow an engineer to coordinate braking and acceleration, as well as redistribute power as they see fit.
If the train is heading in the direction in which the locomotive end of the train is facing, this is considered 'pulling'. If the train is heading in the opposite direction, this is considered 'pushing' and the motorman or engine driver is located in the alternative cab.
In the thread, Holohan contends that the standard railroad gauge in the U.S.—4 feet, 8.5 inches—derives from the way that rail lines were built in England, where engineers based the width of their railroads on the spacing of road ruts in Imperial Rome, which were in turn designed to accommodate the size of horses' rear ...
The Tier 4 locomotive is designed for a typical lifespan of 25 to 30 years.
The horn's primary purpose is to alert persons and animals to an oncoming train, especially when approaching a level crossing. They are often extremely loud, allowing them to be heard from a great distance. The horn is also used for acknowledging signals given by railroad employees, such as during switching operations.
It is estimated that every year some 5,000 deer are hit by trains all over the country. While those collisions alone lead to widespread delays and damage, the problem is even larger when you include the delays caused by deer that don't get hit by trains too.
When the train enters a certain dead end station, the loco gets detached from the front n takes a loop, goes back n then gets attached back to the train. this is called Loco/Rake reversal.

But, since there will still be unexploited pressure in the cylinder at the end of the stroke, this is achieved at the expense of engine efficiency. In this situation the steam will still have considerable pressure remaining when it is exhausted resulting in the characteristic “chuff chuff” sound of a steam engine.
When greater power is necessary, e.g. when gaining speed when pulling out of a station and when ascending a gradient, the Walschaerts valve gear enables the engine driver to set the cutoff point near the end of the stroke, so that the full pressure of the boiler is exerted on the piston for almost the entire stroke.
