Well, I guess there were a couple of times when Amtrak almost stopped paying its bills. The House of Representatives was actively trying to kill Amtrak during the entire period, so it's not surprising.
It's pretty clear that Downs generated one such cash crisis. It was actually a bigger crisis -- requiring a $2.4 billion cash infusion -- but there was a friendly administration (Clinton) rather than an unfriendly one (Bush II).
Downs got handed a company with a lot of deferred maintenance and delayed capital investment. He converted this into a company with a lot of deferred maintenance and delayed capital investment, and worse cash flow.
This was Downs's statement a year and a half before he was forced out due to Amtrak's ridership and revenue dropping, and the company running out of cash.

DOWNS was the first to use the phrase "glide path", it's there in the statement.
Warrington's reputation among rail fans is probably largely due to Gunn and the Class I freight execs badmouthing him. I can't really blame Gunn; David Gunn has talked a lot of BS over the years, but it gets good political results, so I can't blame him.
Frankly I suspect Gunn of grandstanding in order to get the money. It's his style.
Thomas Downs doesn't seem to have a reputation of any sort among rail fans, oddly. But every time I learn something about his professional record, it's worse than the last thing I learned. He seems to have done a bad job at NJ Transit, too. And as the NJ Commissioner of Transportation. And at the DC Transportation Department. I don't know much about his history at the Triboro Bridge and Tunnel Authority. I'm sure Downs is a well-meaning guy -- every Amtrak President was -- but he did a really poor job. He's now the chair of WMATA, overseeing giant cost overruns, massive delays, and inability to maintain equipment. Which seems to be absolutely typical.
