Metro said it had extra personnel on hand to help clear walkways, platforms and parking garages and lots. On Tuesday night, Metro canceled its door-to-door driving service for disabled riders. The transit agency changed some bus routes throughout the region to avoid roads with curves and hills and warned bus riders to expect some delays, depending on road conditions.

On Metro’s rail lines, trains ran as normal both above and below ground in the morning rush. But they were not as crowded because the federal government and many area offices were closed.

Dan Stessel, a Metro spokesman said Wednesday morning that ridership was “anemic” compared to the typical weekday traffic of roughly 800,000 ridership trips a day.

If conditions get worse throughout the day, Metro said it would consider reducing or possibly suspending bus service.
