The Mughal capital

Delhi is an enormous, ancient-and-modern capital built across the plains of northern India, layered with the remains of multiple historic capitals alongside the planned colonial-era core of New Delhi. The Delhi Metro is one of the largest rail networks in the world, and its Airport Express line runs nonstop from Indira Gandhi International toward the New Delhi Railway Station area in about 20 minutes. Air quality drops sharply in winter, when smog from crop-burning and weather inversions can blanket the city for weeks. Outside the metro's reach, Delhi's roads carry some of the densest traffic of any capital, so journeys off the rail network take real planning.

A capital of villages

London is a vast, low-slung capital that grew by absorbing villages, so it reads as dozens of distinct neighborhoods rather than one grid. The Underground and a dense rail network make it a transit city at heart; in the center a car is a liability, discouraged by narrow streets and the congestion charge. The landmarks and business districts cluster in the middle, but much of London is the high streets and parks further out. It is large, so crossing town takes longer than the map suggests.

City access

Heathrow is the main airport, west of London and among the busiest in Europe. It has a fast dedicated rail link to the center and is also on the Underground, so reaching the city without a car is straightforward. Allow extra time at peak hours, both on the roads and through its large terminals.
