1879, the line was extended further north from 104th Street and Columbus Avenue, curved east at 110th Street, and then turned north onto Eighth Avenue to 125th Street. A new station at 116th Street, above Eighth Avenue, was opened. This curve from 110th Street to Eighth Avenue was the highest ever built at above the street and made a 90-degree turn from Ninth Ave on to 110th Street, then another on to Eighth Avenue. It was dubbed "Suicide Curve" as some people leaped to their death from this location. In October 1879, the rebuilding of the lower portion of the line from 14th Street to Morris Street began. The Little West 12th Street station was probably closed at this time. The Morris Street station was closed again as the structure there was rebuilt for the junction to the IRT Sixth Avenue line. The Ninth Ave line narrowed to two tracks and the two tracks of the IRT Sixth Avenue Line on Trinity Place curved onto Greenwich Street to make a four-track structure, where the Sixth Avenue El ramped two blocks south to the level junction just north of the Battery Place Station. On September 27, 1879, the 130th and 135th Street stations on Eighth Avenue were opened. On December 1, 1879, the 145th Street and 155th Street stations were opened. A yard was built on the east side of Eighth Avenue at 145th Street. On May 2, 1880, work was completed on the lower portion of the line and trains began operating over a completely rebuilt structure. The original track on the east side of Greenwich Street and the west side of Ninth Avenue, as well as the sections reinforced between 1874 and 1876, were torn down section by section and replaced. During this reconstruction, service was maintained by using the passing sidings, which, in some cases, became center passing tracks. The Battery Place station replaced the Morris Street station at the junction with the Sixth Avenue line. In the 1880s and the early 1890s, the Ninth Ave El was closed from 8 PM to 5:30 AM and all day on Sundays. In 1880, the fare was raised to 10 cents, but 5 cents during morning and evening rush hours. In 1885, the first demonstration of an electric traction engine in New York was on the Ninth Avenue El. In 1886, the fare was cut to 5 cents all the
