What is the consequence of failing to isolate excess units when HPT exceeds scheduled limits?

When high power testing (HPT) exceeds scheduled limits and excess units are not isolated, it can lead to a range of negative consequences. The first consequence is delays in cargo delivery, as the railway operations may need to be adjusted or slowed down to manage the excessive power, affecting transportation schedules and overall delivery times.

Furthermore, there could be potential fines for non-compliance with regulatory limits. Railroads are required to adhere to specific operational standards, and failing to isolate excess units when necessary may result in violations of these standards, leading to financial penalties.

Additionally, not isolating excess units can lead to increased fuel consumption. The engines working beyond their ideal limits tend to run less efficiently, expending more fuel than necessary, which can escalate operational costs and contribute to greater environmental impact.

Therefore, all these consequences are interconnected and highlight the importance of isolating excess units to maintain efficient operations and compliance with regulations.
