LONDON — It was hardly a blizzard, but it still shut down the city that beat the Blitz.
The biggest snowfall to hit London in 18 years idled the city's trademark red buses and Underground trains Monday, stranded thousands of airline passengers, and raised the vexing question of why a predicted winter storm caught authorities so unprepared.
Transit officials had nearly a week to get ready, but they failed to keep things running normally in the capital, which was buried under more than four inches of snow overnight and another four inches in the afternoon.
Londoners who needed to get somewhere often found they couldn't — unless they were willing to walk for miles.
"There's no point in going to work today," said office worker Caroline Samuel after waiting for an Underground train that never arrived. "I'm going home."
All five of the capital's airports briefly shut down — with nearly 800 flights canceled throughout the day and thousands of passengers stranded. An international flight skidded off a taxiway at Heathrow, causing no injuries.
Buses kept off streets
The city's extensive bus network was completely closed for most of the day and many trains simply didn't run.
Colossal traffic jams clogged roads because of fender benders and more serious accidents.

Some people strapped on cross-country skis to get around; others spent the day sledding with their kids.
Problems extended to France and Ireland as well, with airports in both countries reporting numerous delays and cancellations and motorists facing icy hazards.
London Mayor Boris Johnson conceded that the city lacked the plows and other equipment — mostly because buying it is a gamble with big snowfalls so rare here.
The usually upbeat mayor said "the volume of snow was so huge" that the city's efforts to keep up were doomed and that skidding buses could become "a lethal weapon."
The mayor's official spokesman denied that concerns about insurance coverage led to the decision to keep the buses off the streets.
"It never got that far," said the official, who spoke on condition of anonymity in line with department policy. "It was a basic safety issue. It might have caused some inconvenience, but it's nothing compared to the damage that could be done by a 12-ton vehicle cruising over crushed ice. The roads weren't fit."
Richard Tracey, a Conservative Party member of London's city council, told the British Broadcasting Corp. that the bus company's willingness to deal with snow is different than in past years because of growing levels of health and safety legislation.
"I think the public are prepared to go out, but the bus drivers and the companies won't drive if there's even the tiniest risk of the bus skidding and people being injured," Tracey said. "Government legislation, European legislation and all that, that's what stops these things."
Former Mayor Ken Livingstone blasted London's storm preparations. He said it had been more than a century since the city buses were idled.
Prime Minister Gordon Brown said the government was doing "everything possible" to keep transit systems operating.
The harsh conditions led to hundreds of school closures, and many courts shut as well, including London's landmark Old Bailey. Hospitals remained open, but staffing levels were reduced.
Even Underground gets hit
Harried transport officials defended the system despite its near total breakdown.
The Underground subway network was hard hit because much of the system is actually above ground — and when even one line gets shut down, it has a domino effect on the others.
A Transport for London spokesman said the agency must largely rely on London's local councils to treat roads — and that not all of the councils have the same level of ability to deal with a heavy snowfall.
"We're not in Russia here," said Guy Pitt, a press officer for the agency. "We don't have an infrastructure built for constant snow."
There were reports of some storm-related injuries. A 17-year-old pedestrian was struck by a car in East Sussex, and three teenagers were hospitalized Sunday night after their car collided with another vehicle after hitting a patch of ice.
In Scotland, two members of an ambulance crew responding to an emergency call suffered minor injuries after their vehicle overturned in snowy conditions.
Heavy snowfall in France also disrupted traffic and caused delays at Paris' Charles de Gaulle airport.
Flights to and from Ireland were also affected.
