Will it be a Monorail or metro rail for Visakhapatnam?

The recently announced State Budget of Andhra Pradesh has allocated funds for setting up monorail in Visakhapatnam. State Finance Minister Buganna Rajendranath Reddy, who delivered his first Budget speech in the Andhra Pradesh Assembly.
The implementation of the monorail project is aimed at facilitating the increasing demand for public transport in an eco-friendly way. A comparatively lesser utilisation of land resources and lower construction cost per km are a few of the major advantages of the proposed transport system. While the construction cost per km of metro rail is estimated at Rs.195 crore, the same for a monorail is likely to range about Rs.140 crore. 
While the announcement of the monorail is being welcomed by a few who opine that the system would be suited for a city like Visakhapatnam, it has parallel raised doubts on the fate of the much-awaited metro rail project. 
It may be noted that plans were made to establish metro rail in Visakhapatnam over a distance of 42 km al
