Jeanice McMillan, 42, of Springfield, Va., was to be remembered Friday morning at the Temple of Praise Fellowship Hall in D.C. Her brother and members of her local union are expected to speak.
McMillan and eight passengers were killed in the crash when her train barreled down the tracks and hit a stopped train. About 70 people were also injured.
The train was on automated control at the time of the crash and investigators say they there is evidence McMillan applied the emergency brake before the accident.
Investigators said Thursday the computerized signaling system failed to detect a test train stopped in the same place as one that was struck during the crash.
