I want to know the answer to the following question:
On what hill did construction of Lutyen's Bungalow Zone begin?
All the background I'm provided with is that "Before construction could begin on the rocky ridge of Raisina Hill, a circular railway line around the Council House (now Parliament House), called the Imperial Delhi Railway, was built to transport construction material and workers for the next twenty years.". Is that enough to answer the question?
Answer: yes
