GREENWICH - Just as Metro-North rolls out its new schedule, a fire in Greenwich has officials warning there may be some delays this week on the New Haven line.

Metro-North officials say riders can expect 10-minute delays for at least a week because of the blaze that destroyed a building in Cos Cob Saturday.

The building housed equipment used to signal and switch trains.

Officials say that the tie-ups run between Port Chester and Stamford. They also say it will only affect commuters during rush hour.

The railroad says it is trying to figure out what caused the fire.

Changes on the new schedule were meant to ensure more on-time trains and a shorter commute.
