@Number 90 posted:Okay, before we attempt to solve the cause(es?) of this derailment from the comfort of home,
let's think about how many there could be. These are some of the causes of past derailments of passenger trains:
- Broken rail
- Broken frog
- Broken or missing joint bar and/or bolts
- End-battered rail or low joint
- Missing spikes, tie plates, or broken ties unable to retain spikes
- Insufficient or washed-out ballast
- Improper cross level
- Excessive speed
- Slid flat wheel building up a false flange
- Something falling off of this train or a preceding train
- Failure of a truck component
- Roller bearing retainer strap missing
- Track misalignment due to heat or insufficient maintenance, or excessive speed through turnout by a preceding train.
- Bent, broken, or improperly adjusted point rail of turnout
- Broken connecting rod on turnout
- Broken wheel or wheel flange
- Obstruction on track, especially at turnout
- Improperly installed, maintained, or repaired signal or dual controlled switch circuitry or mechanisms.
Hi Tom:
There is one cause missing from your list.
Criminal Event.
If this is the cause the NTSB, National Transportation Safety Board will turn it over to the. FBI, Federal Bureau of Investigation and DHS, Department of Homeland Security.
I took this photo at Pontiac Station this past Saturday at 6:47 PM - This was just a few hours after this crash. They’re maybe a connection. Just speculation.
