In yesterday's The New York Times, Patrick McGeehan provided numbers on that Amtrak fare increase:

...Amtrak plans to sharply reduce the discount it offers to the thousands of Northeastern commuters who buy monthly passes and 10-trip tickets. Under that plan, the monthly tariff for some will rise $150 to $200 on Oct. 16 and an equal amount in February.

For example, the price of a monthly pass that allows unlimited use of certain trains between Philadelphia and Pennsylvania Station in Manhattan will rise by $188 to $821 next month, then increase again to $1,008 in February, said Bill Schulz, a spokesman for Amtrak in Washington....

$633 to $1008. That's an increase of 59% in three months.

McGeehan added this:

... some elected officials in Washington said they were surprised that Amtrak revived the plan one day after President Bush had called on Americans to conserve fuel.

Surprised? I'm not surprised. Disgusted, yes. Not surprised.
