What is the scheduled HPT for a train operating with symbol Z-LASROC2-20?

The scheduled HPT (High-Power Time) for a train operating with the symbol Z-LASROC2-20 is 3.0. High-Power Time refers to the amount of time a train is expected to operate in a high-power mode, which is critical for ensuring that locomotives can adequately pull loads, especially over challenging terrain or during certain operational conditions.

In the context of this symbol, the schedule indicates that the train should be able to work efficiently within the specified HPT, allowing for optimal performance and fuel efficiency. The designation of 3.0 suggests that this is a well-established, standard parameter for this type of train operation, reflecting its expected power requirements while considering factors such as train weight, gradient, and environmental conditions.

The other options provided denote different times, which would not align with the operational characteristics associated with this specific train symbol. Therefore, the correct understanding and application of scheduled HPT are vital for proper train handling and safety practices.
