Need to go through and  and check/add dates

See also New York City Subway timeline, Talk:Transportation to Coney Island, Talk:Brooklyn Bridge. Dates verified against the New York Times are indicated by [NYT article date]. A few are from official service notices; those are linked. Other dates are from various sources and may be inaccurate.

Closing dates are the last day service ran. If service last ran a bit after midnight, I use the last full day. Similarly, if service first ran a bit before midnight, I use the first full day. Bolded stuff was done under the Dual Contracts; ones I need there are:
 * extra tracks:
 * Jamaica Line from merge with line from Broadway Ferry (east end of Williamsburg Bridge) to Broadway Junction (one new track)
 * Myrtle Avenue Line from Broadway to Wyckoff Avenue, including track connection to Jamaica Line (one new track)
 * Fulton Street Line from east of Franklin Avenue to east of split from Canarsie Line, plus short piece of Canarsie Line north of Fulton Street Line (one new track)
 * Brighton Line from Church Avenue to Prospect Park (two new tracks)

The following lines existed by 1904:
 * full Second Avenue Line
 * Third Avenue Line to Bronx Park, with all Manhattan branches and Willis Avenue branch
 * full Sixth Avenue Line
 * Ninth Avenue Line to 155th Street
 * Brooklyn Bridge
 * Broadway (Brooklyn) Line from Broadway Ferry to Lexington Avenue Line
