| Consider the following statements regarding high speed trains: |
| 1. High speed trains are magnetically levitated (MAGLEV) trains that float in air due to opposite pole magnetisation of tracks. |
| 2. There is a greater wear and tear of the tracks of high speed rails. Which of the above statements is or are correct? |
A) Both
B) None
C) Only 1
D) Only 2
Correct Answer: D
Solution :
[d] MAGLEV is not equal to a high speed train, a high speed train is only a more efficient version of conventional track and tyre train. Higher the speed, higher the wear and tear. India has one of the shortest track rails lasting time, due to open bathrooms which are installed in trains. Concept: The main advantage of the high-speed rail is its compatibility with all those thousands of kilometers of the conventional rail already built. For instance, a conventional high-speed train can operate on the dedicated high-speed rail, but it can also operate on a slower regular section equally well. This is typical, for instance, in France, where TGV trains run not only on the dedicated lines, but also on the conventional railroads with lower speeds. This allows for much wider network with direct service and for gradual growth of the high-speed portion of that network with time. For maglev, only what you built is where your trains can run, but nowhere else. As is with any other transit mode, it is an issue of the transportation SYSTEM, which is all too often ignored when people speak about the maglev. Transportation should not be viewed on a line-by-line basis, it is always a system, and thinking of the system integration is often more important than any particular preferences for a short segment of a particular line.
