They’ll probably never sparkle and shine, but subway stations may get noticeably brighter and cleaner.

MTA bosses plan to refocus the agency’s station rehabilitation program from multiyear mega-projects to lower-cost projects that will have quicker benefits.

Jay Walder, the agency’s CEO, said yesterday he got the idea during a visit to upper Manhattan stations on the No. 1 line, where he saw damaged roofs and asked staff if there were plans to fix them.

Walder didn’t like their answer: “We’re never going to get to that.”

He said smaller rehab projects need to be a bigger priority in the MTA’s five-year, $26.3 billion capital plan.
