Question: When did Union Station open?
About the article "Union Station (Washington, D.C.)", section "Opening and operation".

Candidate passages:
Construction of the station began as far back as 1984, during the building of Tsvetnoy Bulvar station which set provisions for the future station, and during the late 1980s was fully underway with plans to open by the late 1990s.
However the dissolution of the Soviet Union in 1991 put a long delay to construction which at time stood frozen, and, despite a few slow restarts, remained derelict.
Only in 2005 when proper funding finally came did the works resume.
The station was opened just in two years, on 30 August 2007. 
Whilst the pace of Metro construction in the Soviet Union was impressive, it did not, and could not foresee the events that would happen when the Soviet Union dissolved and how the financial and social implications would make the Nizhny Novgorod Metro a system with a very difficult future.
So, when the first stage was completed in 1989, construction began on the second one...and that was the state in which the Gorky Metro embraced the 1990s.
The dissolution of the Soviet Union had devastating effects on the economy and people's lives.
Aided with a hyperinflation, almost all funding of expansion of Metros, save Moscow and Saint Petersburg was cut.
Those segments that did open in the early 1990s were mostly completed already and the bankrupt companies and workers struggled to finish them off.
In late 1993 the first two station segment of the Sormovskaya Line was opened in Nizhny Novgorod. 
Erligou is a station on Line 6 and Line 16 of the Beijing Subway in China.
This station did not enter into operation along with Line 6 Phase I on December 30, 2012.
Rather it will open when the construction of Line 16 is finished. 
 New York Penn Station Newark Penn Station North Philadelphia (note that the train did not stop at 30th Street Station in central Philadelphia, instead bypassing it via Zoo Junction) Paoli Harrisburg (engine change from GG1 to diesel-electric units) Baker Street Station (Fort Wayne) Englewood Union Station Chicago Union Station Station stops.
Until 1933 the train stopped to change engines at Manhattan Transfer, nine miles west of New York Penn Station; passengers from downtown Manhattan could ride the H&M train to Manhattan Transfer and board the Broadway there.
After electrification eliminated the engine change the train continued to stop there for downtown passengers until 1937, when the transfer was moved to Newark itself.
