How are slopes marked on roads and railways?
Railroads representation Building and narrow gauge railroads are represented without division according to the number of tracks and type of traction. Areas of railroad with slope more than 20% are marked out by means of stroked conventional character in the form of an angle.
How roadways and railways are connected?
Compared to railways the roadways are very expensive since most roadways transportation is by diesel or petrol both of which are costly. Railways are one of the cheapest modes of transport. Railways have both diesel enegine and electric engine. Roadways are connected immensely to all the places in our country.
Why is the importance of road transport in comparison to rail transport growing in India?
The growing importance of road transport in comparison to rail transport is because of the following reasons: (i) Construction cost of roads is much lower than that of railways lines. (ii) Roads can pass through comparatively more dissected and undulating topography.
What is the reason for the growing importance of road transport vis a vis rail transport?
Lifelines of National Economy The growing importance of road transport vis-à-vis rail transport is rooted in the following reasons: (i) Construction cost of roads is much lower than that of railway lines. (ii) Roads can traverse comparatively more dissected and undulating topography.
What are the 3 types of contour lines?
Contour lines are of three different kinds. They are the Index lines, Intermediate lines and the Supplementary lines.
What is the space between contour lines called?
A contour interval is the vertical distance or difference in elevation between contour lines. Index contours are bold or thicker lines that appear at every fifth contour line.
What is the difference between railway and railroad?
Usage: In most of the English speaking countries including UK and even Canada, the word that is used to refer to a system of trains running on rails made of iron is railways. On the other hand, railroad is the term that is used in the US for trains running on rails.
How is roadways better than railways?

Roadways act as a feeder to other modes of transport, as they provide a link between railway stations, air and sea ports.
Why are roadways preferred over railways?
Roads have edge over railways because: They provide door to door services. the construction cost of roadways is much cheaper than the construction cost of the railways. Roads can be built hilly and dissected regions while it is difficult to lay railway lines on difficult and rugged terrain.

How is a steep grade railway different from a mountain railway?
Unsourced material may be challenged and removed. A steep grade railway is a railway that ascends and descends a slope that has a steep grade. Such railways can use a number of different technologies to overcome the steepness of the grade. Many steep grade railways are located in mountain regions, and are hence also mountain railways.
When is a slope said to be steep?
Slopes can either be gentle or steep. The slope is said to be steep when the land surface is rising/falling sharply and said to be gentle when the rising/falling of the land surface is mild. A gradient is usually used to measure how steep or how gentle the slope is.
Are there slopes on the side of the road?
On new construction, 1V:6H or flatter side slopes are desirable. In some cases, it may not be practical to flatten the entire roadway side slope. In these cases, spot improvements can still improve roadway safety.
What is the slope ratio of a railway?
This is commonly used in Europe to denote the incline of a railway. as a ratio of one part rise to so many parts run. For example, a slope that has a rise of 5 feet for every 1000 feet of run would have a slope ratio of 1 in 200.
