What are the tons per operative axle of dynamic brake (TODB) of the train, rounded to a whole number?

To determine the tons per operative axle of dynamic brake (TODB) of the train, it's essential to understand how to calculate this figure based on the specific details of the train composition, including the weight of the train and the number of operative axles.

The tons per operative axle is computed by dividing the total tonnage of the train by the number of axles that are actively contributing to the braking process. The dynamic brake is a vital element in train handling, as it provides additional braking power without wearing down the wheel brakes, primarily useful in controlling speed, especially on downhill grades.

In this case, the correct answer of 272 represents a rounded figure that accurately reflects the weight distribution across the operative axles, indicating that the train is well-managed in terms of its braking requirements.

The rounding of the number to the nearest whole integer suggests that a precise calculation of the total weight divided by the total number of operative axles resulted in a value that, when rounded, gives 272. This level of precision ensures that train operations remain safe and effective, adhering to regulatory standards and operating guidelines.

This value falls within the acceptable range of dynamics for the type of train in consideration, reinforcing the reliability of the braking system under operational conditions. Understanding
