What the evidence establishes
CLAIM 01The March 10, 1989 subway collision at 103rd Street injured 50 people.
Scope: 103rd Street station on the Broadway subway line, Manhattan, New York City · 1989-03-10 – 1989-03-10
Assessment: REFUTEDThe study gives 50 without a narrower category; the original investigation and agency synopsis give 41 in total. The early approximate account is not treated as a final tally.
What is not established: Other retellings differ. No formal correction, original newspaper source, or cause of the discrepancy established.
CLAIM 02The NTSB’s March 13, 1990 report identified an improperly applied signal jumper wire as the probable cause; delayed proper repairs contributed to the collision, while excess speed, partly attributable to inadequate means of determining speed, increased its severity.
Scope: 103rd Street station on the Broadway subway line, Manhattan, New York City · 1990-03-13 – 1990-03-13
