A new audit finds that subway maintenance facilities in New York City were not safe for employees and slowed down their work.

The MTA Inspector General says inspections on thee roofs and structural conditions were often done by under-trained staff Records show repairs to the roof at one station were proposed as early as the 1980s.

Inspectors say they found vegetation growing through holes in roofs, concrete falling due to water damage and leaks right above electrical equipment.

However, they say NYC transit has already addressed some of these conditions.
