Deadly bomb attacks on rail passengers in Mumbai, India Tuesday led to stepped up security on commuter trains in New York City, Westchester and Hudson Valley.

Officials say eight bombs exploded on trains in Mumbai in a series of coordinated terrorist attacks, killing at least 150 people. As news of the bombings spread, the Metropolitan Transit Authority (MTA) began re-deploying its police force to keep the railroad safe. According to MTA spokesman Tom Kelly, the stepped up security involves police both in uniform and plain clothes throughout its system.

Many commuters at the Croton-Harmon Station, which is one of the busiest on the Metro-North line, say the news of the bombings will not make them change their plans. Police reminded commuters that if they see anything suspicious to report it.
