Amtrak will start randomly screening passengers' carry-on bags this week in a new security push that includes officers with automatic weapons and bomb-sniffing dogs patrolling platforms and trains.
The initiative, to be announced by the railroad on Tuesday, is a significant shift for Amtrak. Unlike the airlines, it has had relatively little visible increase in security since the 2001 terrorist attacks, a distinction that has enabled it to attract passengers eager to avoid airport hassles.
Trains are not planes, and random checks like this are pointless.
