"According to sources at the crash site the incident was caused by a
broken rail, and a member of the rail staff who saw the rail said it was
"rusted" before it fractured."

Out of curiosity (and I accept there may be a perfectly good answer to
this), how can you tell a rail is rusted just by looking at it? Being
steel there's always going to be a fair bit of corrosion on the outside,
with only the tops being polished clean by passing trains.
