It is important that interpretation of the discount clause in the FY06 funding legislation is up to Amtrak to interpret and the Inspector General's office to enforce. If the Secretary of Transportation views the "70% of the full fare bucket" is in violation of the law as listed on the current Railsale listings, Amtrak must discontinue the pricing system that lists fares greater than 50% as stated by law.
Although I agree with your interpretation of the discount clause of the funding legislation, Amtrak will be scrutinized by DOT for providing any discounts to listed to the public greater than 50%, regardless of the fare bucket being discounted. With the Amtrak Board of Directors being the same as last year, I believe we'll see the current Railsale program disappear the last few weeks of February to be compliant with the funding legislation. I don't see management trying to improve ridership with discounts since this board will try to raise fares fees and cut food and beverage service levels to build up the bottom line. This is the traditional method of Big Business board of directors, especially those in the airline industry, in reforming a company's financial troubles. This board has made it clear that increasing ticket fares, cutting food and beverage services, reducing first class emenities like sleepers and entertainment activities, eliminating labor, etc. is their answer for Amtrak. David Gunn believed the opposite and managed the company differently and he got fired!
Just keep on smiling, hope for the best and keep riding the trains.
