1. The main function of sleeper is

- to support rails
- to hold rails at correct gauge
- to distribute load from the rails to the ballast
- all of these

2. “Composite Sleeper Index” is relevant in determining

- Required and adoptable sleeper density
- Durability of sleeper units
- Mechanical strength of the stock of wooden sleepers

Which of the above statements is/are correct?

- ii and iii only
- i and ii only
- i only
- iii only

3. The slope of adzing of sleepers is

- 1 in 30
- 1 in 25
- 1 in 20
- 1 in 15

4. The density of sleepers mainly depends upon all except one of the following

- Axle load the rail track is designed to carry
- The nature of sleeper and the materials used
- Lateral thrust of locomotives
- Speed of the train
- Climatic variations

5. Standard size of wooden sleeper for Broad Gauge track is

- 225 x 23 x 13 cm
- 250 x 26 x 12 cm
- 200 x 26 x 12 cm

- 500
- 750
- 600
- 650

7. To provide a cant in rails, wooden sleepers are cut to a slope at rail seat, which is known as

- Cutting
- Coning
- Adzing
- Boxing

- 1455
- 1352
- 1555

12. What do you mean by a sleeper density of M+7, in railway engineering?

- Number of sleepers required per kilometer length = 1007
- Number of sleepers between any two stations = (distance in km + 7)
- Number of sleepers per rail length = (length of rail in meters + 7)
- Spacing of sleepers = 107 cm c/c

13. The number of sleepers used for rails varies from, where ‘n’ length of rail in ‘m’

- (n + 1) to (n + 4)
- (n + 3) to (n + 6)
- (n + 2) to (n + 7)
- (n + 4) to (n + 8)
