The Past Perfect Continuous tense is like the Past Perfect tense, but it expresses longer actions in the past before another action in the past. For example:
Shalini started waiting at 10 am. Sirisha arrived at 12 am. When Sirisha arrived, Shalini had been waiting for two hours.
Here are some more examples:
Prakash was very tired. Prakash had been running.
They could smell cigarettes. you had been smoking.
Suddenly, my scooter broke down. I was not surprised. It had not been running well for a long time.
