Railway and Airport Engineering — Winter 2023

Define permanent way and elaborate the requirements of ideal permanent way.

Demonstrate various types of stresses induced in a rail section. Explain briefly how these are evaluated.

Discuss the role of Indian Railways in the social and economic development of the country. Briefly mention the strengths and weaknesses of the Indian Railways.

Explain the functions of fish plates and fish bolts.

If the ruling gradient is 1 in 250 on a particular section of B.G. and at the same time a curve of 4° is situated on this ruling gradient, what should be the allowable ruling gradient?

Calculate the superelevation and the maximum permissible speed for a 2° BG transitioned curve on a high-speed route with a maximum sanctioned speed of 110 km/h. The speed for calculating the equilibrium superelevation as decided by the chief engineer is 80 km/h and the booked speed of goods trains is 50 km/h.

Derive the expressions for equilibrium superelevation.

Explain different types of station yards.

Classify and briefly explain types of railway switch.

Outline different facility requirements of a railway station. Classify the railway stations. Draw a neat sketch of layout of any one type of station.

Summarize the necessity of marshalling yards. Describe the layout of a typical marshalling yard.

Describe the main constituents of a crossing. Draw neat sketches to show a point rail and a splice rail.

Draw a neat sketch of a left-hand turn out and name its various components. Describe any one method of designing a turnout and give the detailed procedure for calculating the lead.

Classify the airport as per ICAO.

Describe the airport terminal building with help of the sketch.

Describe various components of air traffic control network. OR1

Explain the aircraft dimensions height, wingspan and length using the necessary sketch.

Discuss factors that affect the necessary size of an airport.

State the purposes for installing the visual aids at the airport and the requirements of pilots for the visual aids.

Discuss the points to be considered in the geometric design of a runway

Outline the functions of taxiway in airports. Draw cross sections of taxiway showing all components.

At an airport site at sea-level with standard atmospheric conditions, the runway lengths required for take-off and landing are 2000 m and 2400 m respectively. The proposed airport is situated at an altitude of 150 m. If the airport reference temperature is 25°Cand if the effective runway gradient is 0.35 per cent, calculate the length of runway to be provided.

Sketch various orientation of runway with label

Explain the basic requirements and objectives of surface drainage.

Design an exit runway joining a runway and a parallel main taxiway. The total angle of turn is 35° and the maximum turn-off speed is 80 kmph. Radius of entrance curve = 731m, Runway width = 45m, Taxiway width = 22.5m. Suggest the maximum separation clearance.
