Amtrak’s CEO says full rail service will be restored at New York’s Penn Station by Friday morning.

Speaking Thursday, Wick Moorman says workers are finishing repairs that followed two derailments within two weeks. The repairs have caused major delays for commuters at the nation’s busiest rail hub.

Moorman says the April 3 derailment was caused when a New Jersey Transit train went over a wooden crosstie under the track that was apparently weakened and the track split.

He says an Amtrak train derailed in March because the track was misaligned.

Rail service has been cut back since Monday morning’s derailment took out eight of 21 tracks maintained by Amtrak. The Long Island Rail Road and NJ Transit have been operating on abbreviated schedules since Monday’s derailment.
