Service delays on subway, commuter rail

Boston-area transit riders endured multiple delays Tuesday on subway and commuter rail lines, sparked by mechanical failures, clingy leaves, and signal woes.

During the evening commute, the Newbury/Rockport and Haverhill lines encountered 10- to 20-minute delays because of mechanical failures. The Needham Line experienced delays of up to 45 minutes because of slippery rails, caused by leaves clinging to the tracks.
