The maximum limit of super elevation prescribed by Indian Railways on broad gauge is
Show Hint
Important railway standards:
• Maximum super elevation (BG) \(\approx 165\) mm.
• Cant is provided to balance centrifugal force on curves.
• Maximum super elevation (BG) \(\approx 165\) mm.
• Cant is provided to balance centrifugal force on curves.

The Correct Option is D
Solution and Explanation
Concept:
Super elevation (cant) is the difference in level between the outer rail and the inner rail provided on railway curves to counteract centrifugal force.
According to the Indian Railways Permanent Way Manual,
the maximum permissible super elevation for Broad Gauge (BG) is
\[
\boxed{165\text{ mm}}
\]
which is commonly taken as
\[
\boxed{165.1\text{ mm}.}
\]
Step 1: Recall the standard value. For Broad Gauge, \[ e_{\max}=165\text{ mm} \] (approximately \(165.1\) mm).
Step 2: Select the correct option. Therefore, \[ \boxed{\text{Maximum permissible super elevation}=165.1\text{ mm}.} \] Hence, the correct option is \[ \boxed{(D)\;165.1\text{ mm}.} \]
Step 1: Recall the standard value. For Broad Gauge, \[ e_{\max}=165\text{ mm} \] (approximately \(165.1\) mm).
Step 2: Select the correct option. Therefore, \[ \boxed{\text{Maximum permissible super elevation}=165.1\text{ mm}.} \] Hence, the correct option is \[ \boxed{(D)\;165.1\text{ mm}.} \]
