Question

It would be hard to prepare a time chart for trains in which of the following scenarios?

• A. The train passes through multiple longitudes.
• B. There exists no pre-determined standard time in the said country.
• C. The number of employees in the railways is insufficient.
• D. The train passes through multiple latitudes.

Answer 1

Answer: (A), (B)

The correct options are
A The train passes through multiple longitudes.
B There exists no pre-determined standard time in the said country.

The local time of places which are on different meridians are bound to differ. It is, thus, difficult to prepare a time chart for trains which cross several longitudes. In India, for example, there will be a difference of about one hour and 45 minutes in the local times of Dwarka in Gujarat and Dibrugarh in Assam. It is, therefore, essential to adopt the local time of a central-lying meridian of the country as the standard time for the country.
