I want to know the answer to the following question:
In what year did the Imperial Delhi Railway line begin operating?
All the background I'm provided with is that "The last stumbling block was the Agra-Delhi railway line that cut right through the site earmarked for the hexagonal All-India War Memorial (India Gate) and Kingsway (Rajpath), which was a problem because the Old Delhi Railway Station served the entire city at that time.". Is that enough to answer the question?
Answer: no
