What is the Actual Horsepower per Ton (HPT) of this train, rounded to the nearest tenth?

To determine the Actual Horsepower per Ton (HPT) of a train, you need to know both the horsepower that the locomotive(s) produce and the total weight of the train in tons. The formula for calculating HPT is:

Actual HPT = Total Horsepower / Total Weight in Tons

By following these steps:

1. Calculate the total horsepower generated by the locomotive(s).

2. Determine the total weight of the train, including all cars and cargo.

3. Divide the total horsepower by the total weight of the train in tons.

The result will give you the HPT value. In this case, rounding the calculated value to the nearest tenth yields 2.2, which is why that answer is selected. Understanding how HPT reflects the efficiency and capability of the train in terms of power in relation to its weight is crucial for evaluating train performance. Therefore, the correct choice of 2.2 signifies a well-balanced combination of power and load that meets operational standards.
