a) Maximum length of rail vehicle
b) Maximum height and width of rail vehicle
c) Maximum weight of rail vehicle
d) Minimum height and width of rail vehicle

Explanation: The term “loading Gauge” refers to the maximum height and width of the rail vehicle. This ensures safe passage of trains through tunnels, bridges, platforms, etc. Therefore, a design of railway vehicle is made keeping in mind the limiting values of loading gauge.

2. The term “Rolling Stock” in Railways includes ________
a) Locomotives, coaches and wagons
b) Sleepers, tracks and gauges
c) Wheels and sleepers
d) Tracks and platforms

Explanation: In Railways terminology, the term “Rolling Stock” includes locomotives, coaches and wagons or any vehicle that runs on rail tracks. It can include both powered and unpowered vehicles. The rolling stock can act as an engine (for eg. locomotive) or can be used to carry passengers (for eg. coaches) or can be used to carry goods (for eg. wagon).

3. As per the Indian Railways, the maximum height and maximum width of the rolling stock for Broad Gauge (BG) is _____ mm and _____ mm respectively.
a) 3455 mm and 2745 mm
b) 4140 mm and 3250 mm
c) 4830 mm and 3600 mm
d) 3455 mm and 3250 mm

Explanation: According to the Indian Railways, the maximum height and maximum width of rolling stock for Broad Gauge (BG) is 4140 mm and 3250 mm respectively and for Metre Gauge (MG), the values are 3455 mm and 2745 mm. These dimensions should be strictly followed and maintained while designing the rolling stocks for Indian Railways.

4. What does a construction gauge mean?
c) Maximum length of the rolling stock

Explanation: A construction gauge refers to the loading gauge plus the extra clearance or necessary clearance given to the loading gauge so that the train can pass safely at the same speed without any stoppage. Therefore, construction gauge = loading gauge + extra clearance.

5. The bridges and tunnels are built with respect to ______
b) Narrow gauge
c) Construction gauge
d) Cape gauge

Explanation: A rolling stock is built in accordance to the loading gauge. This rolling stock should pass through bridges and tunnels without any collision or contact. Therefore, an extra clearance in addition to loading gauge is used while designing the bridges and tunnels. This is known as construction gauge. Hence, the bridges and tunnels are built with respect to the construction gauge.

6. Which locomotive in India is listed in “Guinness Book of World Records” for being the oldest operational steam locomotive?
a) Fairy Queen
b) DHR 778
c) Indian locomotive class SG
d) Nilgiri Mountain Railway X class

Explanation: The East Indian Railway Nr. 22, popularly known as the “Fairy Queen” is the oldest steam locomotive which is still operational and is listed in the “Guinness Book of World Records”. It was built in the year 1855. It runs between New Delhi to Alwar.
