RONKONKOMA - Normal service was restored this afternoon to the Long Island Rail Road's Ronkonkoma branch following Monday‚Äôs freight car derailment in Wyandanch.

The freight car was carrying 100 tons of lumber when it derailed Monday morning and crushed a signal box, just west of the Wyandanch station.

The box held hundreds of signal wires for 28 switchers. Those switchers control the speed of the trains and the operation of crossing gates.

Trains had been forced to slow down while railroad crews repaired the signal box.
