Hell Gate Bridge, Astoria Park

Astoria Park is a 59.96-acre (24.3 ha) New York City park on the Queens bank of the East River, and the railway crosses straight over it. The Hell Gate viaduct enters the park's northeast corner on steel deck-girder spans and runs on toward the arch over the water, so a visitor stands underneath the line as well as beside it.

The vantage point given here, on the lawn about 130 m (430 ft) southwest of the nearest Northeast Corridor track, is the compromise most people end up at: close enough that a train on the viaduct fills a short telephoto frame, far enough back that the arch span 256 m (840 ft) to the north-northwest still fits in a wide one. Walking northeast brings you directly beneath the girders, where an Acela passing overhead is felt as much as seen; walking southwest onto the open lawn trades that for the full profile of the bridge against the Manhattan and Randalls Island skyline.

This is a busy municipal park rather than a lineside pull-out. On a summer weekend the lawns, the pool, the running track and the tennis courts are all in use, and a photographer with a long lens is unremarkable among them. Nothing about the place is railway property and nothing is fenced off for railfans: you are a park user who happens to be watching trains. Benches along the shoreline path are, in the words of the NYC Parks description, "popular spots year-round".

There is no lineside noise to listen for and no radio chatter worth scanning. Trains simply appear on the viaduct, cross, and are gone -- the whole sequence takes seconds at Northeast Corridor speeds.

The setting is water, steel and skyline rather than countryside. The park sits on the edge of Hell Gate, the tidal strait where the East River, the Harlem River and Long Island Sound meet, and the current runs hard and visibly through it. Two great bridges frame the view: the Hell Gate Bridge to the north-northwest, painted a deep red the city knows as "Hell Gate Red" since the repainting was completed in 1996, and the Robert F. Kennedy (Triborough) Bridge 0.88 km (0.55 mi) to the northwest.

The arch itself is the dominant object. Its main span is 1,017 ft (310 m) of steel through arch, and the structure including its approaches runs 17,000 ft (5,200 m) -- so from the park you see only the beginning of it, the viaduct marching away southeast over the streets of Astoria on masonry piers and girder spans.

Light on the river is the changeable element. Morning gives flat, cool light off the water; late afternoon throws the arch into profile against a bright western sky, with Randalls Island and the Manhattan shore behind. Gulls, tugs and the occasional Circle Line boat pass below the span. The park's own planting -- mature London planes and oaks across the lawns, more than a thousand mapped trees on the site -- supplies foreground and, in autumn, colour that the steel does not.

The bridge was built by the New York Connecting Railroad to link the Pennsylvania Railroad's Long Island network with the New Haven Railroad, and through it New England. Construction was overseen by the engineers Gustav Lindenthal, Othmar Ammann and David B. Steinman, with architect Henry Hornbostel responsible for the masonry towers. The bridge was dedicated on March 9, 1917, and the first train ran across it at that ceremony. Its main span of 1,017 ft (310 m) made it the longest steel arch in the world at the time.

The park is very slightly older than the railway across it. The City of New York acquired more than 56 acres along the river in October 1913, while the bridge was still under construction, and the Board of Aldermen officially named it Astoria Park in December 1913 -- it had been called William J. Gaynor Park, then East River Park. The park was enlarged twice afterwards, with a four-and-a-half-acre parcel beneath the RFK (Triborough) Bridge in 1937 and the five-acre Ralph DeMarco Park strip along the river in 1969.

The water below carries its own history. On June 15, 1904, the steamer General Slocum caught fire in the East River carrying the congregation of St. Mark's German Lutheran Church; at least 1,021 of about 1,300 passengers died before the ship grounded on North Brother Island -- New York City's worst maritime disaster, and it happened in sight of this shore.

The line itself remains in the middle of a change. Amtrak is contributing 500 million dollars to the MTA's Penn Station Access project, which is rebuilding the Hell Gate Line, adding eight miles of new track and four new interlockings, and rehabilitating four bridges, with Metro-North service to Penn Station due in 2027.

Very few places let you watch a mainline railway from a municipal lawn with a swimming pool behind you. The viaduct crosses public parkland, so there is no trespass question to weigh and no landowner to negotiate with -- an unusual combination for a structure of this size.

The traffic mix is also unusual. The same three-track structure carries 12.5 kV electric Acela and Northeast Regional trains on two tracks and unelectrified CSX freight on a third, immediately adjacent. Few places in North America put high-speed electric passenger service and carload freight on the same bridge.

And this is one of the very few surviving points where the Northeast Corridor is genuinely photogenic inside New York City. East and west of here the corridor is in tunnel, in cutting or behind fencing; across Hell Gate it is on open steel, high above water, in the open air.

The FRA's own bridge inventory records the spans crossing the park streets under Amtrak's ownership (owner code AMTK) -- the nearest of them, over Shore Boulevard 152 m (500 ft) from this point, is listed as a steel through truss, distinct from the steel deck girders that carry the rest of the approach.
