Can maglev go uphill?

And also because it can travel up higher ascending grades (up to 10 percent), compared to conventional trains (up to 4 percent or less), maglev trains can also reduce the need to create new tunnels or to level the landscape to build its tracks.



Yes, Maglev (magnetic levitation) trains are actually superior to conventional "wheel-on-rail" trains when it comes to climbing hills. Because maglevs do not rely on friction between a wheel and a track for traction, they can handle much steeper gradients. A traditional high-speed train typically struggles with gradients over 4%, whereas maglev systems can easily ascend slopes of 7% to 10%. This capability is due to the electromagnetic propulsion system, which pulls or pushes the train along the guideway regardless of the incline. This is a massive engineering advantage because it allows maglev tracks to follow the natural terrain more closely, reducing the need for expensive, environmentally disruptive tunnels and deep "cuts" through hills. In mountainous regions, this makes maglev a more flexible—though significantly more expensive—infrastructure choice compared to standard high-speed rail.

On 22 September 2006, a Transrapid magnetic levitation (or maglev) train collided with a maintenance vehicle near Lathen, Germany, killing 23 people. It was the first fatal accident involving a maglev train.

The design of the guideway -- whether the German “T” shape for the wrap-around vehicle or the Japanese “U” shape with the vehicle enclosed -- ensures that the trains are safe from derailment. Today, maglev trains are generally considered to be among the most safe and comfortable rapid transit systems in the world.

Pilatus Railway, Switzerland The Pilatus Railway runs from Alpnachstad on Lake Alpnach to the Esel station near the summit of the 6,800-foot-high Mount Pilatus in the Swiss canton of Obwalden. It takes the crown as the world's steepest rack railway with a maximum gradient of 48 percent.

The Lickey Incline, south of Birmingham, is the steepest sustained main-line railway incline in Great Britain. The climb is a gradient of 1 in 37.7 (2.65% or 26.5‰ or 1.52°) for a continuous distance of two miles (3.2 km).

Due to the huge cost of running a maglev over very long distances, the hovering trains have been ruled out for the planned HS2 line connecting Manchester with London and Birmingham by 2033.

Maglev trains do not have wheels or rails. As shown in Figure 3, they have guideways, and they float down these guideways without ever touching them.

As noted above the Maglev trains are capable of traveling at speeds nearly twice as fast as the bullet trains. However, the use of such extreme speeds in commercial travel seems unlikely. Whereas Maglev trains travel at speeds of up to 400 or 600kph, bullet trains travel at a modest 320kph.

Compared to highspeed passenger rail, maglev passenger rail consumes roughly twice the power per passenger kilometer. For commercial freight I found an efficiency figure of 520 ton-miles per gallon (660 kg-km/MJ). Assuming 70kg for the average commuter passenger this gives us an efficiency of (116 kg-km/MJ) for maglev.

SNCF, widely regarded as one of the best high-speed rail operators in the world, has had 4 profitable years and 5 loss-generating years since 2012. The Shanghai Metro Maglev has never been profitable. Clearly, there is an issue with passenger transport. No mode of transportation can consistently generate profits.

Maglev trains require very straight and level tracks to maintain high speeds. This necessitates extensive viaducts and tunneling, making construction costly.
