Are wider train tracks better?
Broader gauge railways are generally more expensive to build, because they are usually heavier in construction, use larger cars and locomotives (larger loading gauge), as well as larger bridges, larger tunnels (larger structure gauge). But broader gauges offer higher speed and capacity.
Why are train tracks that wide?
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 …
Why are train tracks not wider?
Trains typically have wheels that are connected together by a fixed axle, meaning that the wheels on both sides of the train always turn at the same speed. Train wheels aren’t perfect cylinders. They’re beveled to make them wider on the inside.
Why are train tracks narrow and trains wide?
Narrow gauge lines are oftentimes built as a cheaper alternative to a standard or a broad gauge line. Narrow gauge railway utilize lighter rail, tighter curves, and less expensive infrastructure such as bridges and tunnels.
Can trains be wider?
A broad-gauge railway is a railway with a track gauge (the distance between the rails) broader than the 1,435 mm ( 4 ft 81⁄2 in) used by standard-gauge railways.
How wide is train track?
4 feet, 8.5 inches
How wide are railroad tracks? The US standard railroad gauge is 4 feet, 8.5 inches (Gauge means width between the two rails). The U.S. federal safety standards allow the standard gauge to vary from 4 ft 8 in (1,420 mm) to 4 ft 9 1⁄2 in (1,460 mm) for operation up to 60 mph (97 km/h).
How wide is railway track?

How do trains stay on the track?
The wheels on each side of a train car are connected with a metal rod called an axle. This axle keeps the two train wheels moving together, both turning at the same speed when the train is moving. This is where the wheels’ geometry comes in. To help the wheels stay on the track their shape is usually slightly conical.
How wide is a train?
Ten feet, three inches, in American measurement. 3.11 meters, in metric measurement. That is the total width of the outside of the locomotive cab and most freight cars.
What are the advantages of wider railway tracks?
Wider tracks has many advantages; we can have more stable trains, more interior options and increase of passenger/freight load per km of rail track. Technology has advanced considerably from the 7′ Brunel track made 150 years ago. We should invest for the f I have certain thoughts to share here..
How do trains stay on the tracks when they turn?
As a result when a train is turning it is momentarily running on wheels that are effectively two different sizes. As the outside wheel’s circumference becomes larger it is able to travel a greater distance even though it rotates at the same rate as the smaller inside wheel. The train successfully stays on the tracks!
What keeps the train wheels moving at the same speed?
This axle keeps the two train wheels moving together, both turning at the same speed when the train is moving. This construction is great for straight tracks. But when a train needs to go around a bend the fact that both wheels are always rotating at the same rate can become a problem.
How can I make trains wider?
If you were prepared to rebuild every tunnel, station etc then you can make trains much wider and use the same guage. Dedicated high speed lines do exactly that. You could use wider guage and make the train even wider (perhaps like a wide body plane with two aisles!) but at the expense of even more building work.
