As soon as the accident was reported to it, Metro-North suspended service in the affected area between Marble Hill and Spuyten Duyvil.
Passengers on the #781 train, or already waiting at Marble Hill, were taken back to the Yankee Stadium station south of Highbridge Yard and discharged.
Some complained they were offered neither an explanation or alternatives, although Metro-North began offering shuttle bus service between Marble Hill and Riverdale, the next station north of Spuyten Duyvil, by midnight.
It also announced that Hudson Line tickets would be cross-honored on the Harlem Line, which parallels the New York–Connecticut state line through the same three counties.

Metro-North crews began working within hours to assess the damage.
By morning rush hour, the railroad had suspended all service on the Hudson Line south of Yonkers, three stations north of the accident site, until cleanup and repairs could be completed.
In the meantime, it arranged bus service from Yonkers to the Van Cortlandt Park – 242nd Street station, the northern terminus of the New York City Subway's 1 train, which many Hudson Line passengers disembark to at the Marble Hill station to reach jobs on the West Side of Manhattan.
Howard Permut, president of Metro-North, promised riders that normal service would resume by July 22, the next Monday, four days after the accident.

The next morning, a Friday, posed a challenge for regular Hudson Line commuters.
Some riders, particularly those who normally took trains to Grand Central, more convenient to the East Side and Brooklyn, chose to drive in instead or take the day off, giving themselves an unanticipated three-day weekend.
Those that took the train anyway were mostly late for work, since the detours added as much as an hour and a half to their commutes.
A Poughkeepsie woman interning on Wall Street told The New York Times she did not bother calling her superiors to explain why she was late, since "[t]hey take the train too."
Metro-North estimated that Hudson Line ridership was half of what it otherwise might have been that day.

Throughout the day and following weekend cleanup continued.
That task was complicated by the location of most of the derailed cars in a short, narrow rock cut.
Cranes and other heavy equipment used to lift cars back onto the tracks, and the spilled containers back on them, had to be laboriously repositioned after each use due to the limited space available, adding hours to the job.
Some of the flatcar trucks were badly damaged in the accident and had to be repaired in situ to make them usable again.
Workers also had to contend with the continued hot and humid weather.
Some containers had also opened in the accident, spilling their contents, which had to be repacked. "
It's not like pickup sticks", explained a Metro-North spokeswoman.

Crews from Metro-North, assisted by subway workers, worked around the clock through the weekend.
After clearing the wrecked flatcars and reloading the containers, they had to repair a 1,500-foot (460 m) stretch of track.
By Monday morning Metro-North was able to keep Permut's promise and reopen one of the two main tracks affected.
It was able to handle 40 inbound and 12 outbound trains, mostly during the morning and evening rush hours.

Work continued throughout the week on the other track.
It was necessary to suspend service again over the next weekend, starting on Saturday morning to avoid disrupting service for fans headed to a New York Yankees home baseball game on the night of July 26, a Friday.
By the evening of Monday, July 29, the tracks had been completely cleared and fully repaired.
Service on both tracks was restored to normal.
