Metro's new general manager wants to get rid of the carpet in trains, brighten the lighting in stations and increase advertising in stations, trains and buses.

In many places, such mundane changes would be met with a shrug.

But this is the Washington area Metro, which has long prided itself on a dignified ambiance that is supposed to make it better than the average commuter system.

The changes are intended to help make the nation's second-busiest subway more modern and functional. As the system struggles to keep pace with growing demand, Metro's new top executive, John B. Catoe Jr., wants to focus the agency's limited resources toward moving people to and from work and away from some costly features that gave the subway a distinctive, first-class feel when it opened 31 years ago.

With ridership continuing to swell, the debate over those trade-offs is sharpening.
