Question 1. A broad gauge railway line passes through a horizontal curved section (radius = 875 m) of length 200 m. The allowable speed on this portion is 100 km/h. For calculating the cant, consider the gauge as centre-to-centre distance between the rail heads, equal to 1750 mm. The maximum permissible cant (in mm, round off to 1 decimal place) with respect to the centre-to-centre distance between the rail heads is_______      [2019 : 2 Marks, Set-II]
Solution:

Question 2. For a broad gauge railway track on a horizontal curve of radius R (in m), the equilibrium cant e required for a train moving at a speed of V(in km per hour) is    [2017 : 1 Mark, Set-II]
(a)
(b)
(c)
(d)

Solution:

Question 3. A runway is being constructed in a new airport as per the International Civil Aviation Organization (ICAO) recommendations. The elevation and the airport reference temperature of this airport are 535 m above the mean sea level and 22.65°C, respectively. Consider the effective gradient of runway as 1%. The length of runway required for a design-aircraft under the standard conditions is 2000 m. Within the framework of applying sequential corrections as per the ICAO recommendations, the length of runway corrected for the temperature is     [2017 : 1 Mark, Set-I]
(a) 2223 m
(b) 2250 m
(c) 2500 m
(d) 2750 m
Solution: Elevation = 535 m
Airport Reference Temperature = 22.65° C
Runway length = 2000 m under standard conditions.
Runway length correction for T°C.
=> Correction for elevation

Corrected runway length = 2249.67 m
=> Corrected standard T° at 535 m elevation
= 15°C - (0.0065 x 535) = 11.52°C
Correction for T°

Corrected Runway length
= 2249.67 + 250.39

Combined elevation and temperature correction
= 500 m < (0.35 x 2000)

## FAQs on Past Year Questions: Railway & Airport Engineering - Transportation Engineering - Civil Engineering (CE)

 1. What is the purpose of railway engineering?
Ans. Railway engineering is a specialized branch of civil engineering that focuses on the design, construction, and maintenance of railway systems. Its main purpose is to ensure the safe and efficient movement of trains, passengers, and goods.
 2. What are the key factors considered in airport engineering?
Ans. In airport engineering, several key factors are considered, including runway design and length, terminal building design, air traffic control systems, navigation aids, safety measures, and environmental considerations. These factors are crucial for the smooth operation and safety of airports.
 3. How are railway tracks designed?
Ans. Railway tracks are designed to meet specific requirements such as train weight, speed, and traffic volume. The design process involves determining the track alignment, selecting appropriate rail and sleepers, calculating the required track geometry, and considering factors like drainage, ballast, and subgrade stability.
 4. What are the challenges in airport engineering?
Ans. Airport engineering faces various challenges, including the need to accommodate increasing air traffic, ensuring runway safety, managing environmental impact, integrating advanced technology and infrastructure, and optimizing passenger flow and comfort. These challenges require careful planning and innovative solutions.
 5. What are the different types of airports?
Ans. Airports can be classified into several types based on their size, purpose, and facilities. Some common types include international airports, regional airports, domestic airports, military airports, and private airports. Each type serves a specific set of requirements and has distinct features.
