Is there an authority that maintains the bike rack?

The same type of thing happens at the commuter rail stations for the trains that provide service into Boston. At one station that I used to use quite a bit, there was one bike that had been locked to the rack for years, the chain was so corroded and it was like one giant chunk of steel, and finally it got to the point that someone even stole the back rim.

After mutilple complaints, the MBTA, who oversees the parking lots at the station, finally did something about it.

The bike rack in South Station in Boston is in the same condition, some of the bikes on that rack haven't moved in years.

I think 1/2 the bikes that are locked to public racks in the city of Boston are abandoned. They are an eyesore, nevermind something that just takes up space, and prevents legitimate riders from using the racks.
