In 1929, the Delaware, Lackawanna and Western Railroad, the owners of the railway at the time, spent $100 million to electrify the Morris & Essex lines. This meant that Chatham station would be electrified and would be served by electric trains, some of the first in the United States. During summer 2007, operator New Jersey Transit replaced the tracks at Chatham along with those on the rest of the Morristown Line, upgrading them to have more advanced and reliable concrete ties rather than older wooden types. The exterior of the station recently went under renovation. Some of the renovations the station received included a new paint job and a new roof.
