Obama also got tons of money appropriated for rail. Here's a sympathetic write-up from 2014: https://time.com/3100248/high-speed-rail-barack-obama/
Headline projects were CAHSR, Florida HSR, and Wisconsin HSR. Republican governors sent the money back in Wisconsin and Florida, and that got sent to CAHSR and Acela, mostly.
Some lowlights from projects mentioned in the article:
- "it’s bringing trains to the Illinois towns of Geneseo and Moline for the first time since 1978" - still no train despite at least $400m in federal funding
- "By 2017, the program will reduce trip times from Chicago to St. Louis by nearly an hour through upgrades that will increase top speeds from 79 to 110 miles per hour" - $1.66bn in federal dollars later travel times are now half an hour shorter as of last year
- "Chicago to Detroit will get a similar boost" - 80 miles of Amtrak-owned track were improved from 79mph to 110. It's saved about 20 minutes after over a decade.
The money got spent, but not efficiently and not on anything new. The Obama admin's obsession with spreading the money everywhere out of some awful instinct that it would get them Republican buy-in just resulted in terrible kneecapped projects. Hell, even some of the money that went to states that wanted it (California) mostly got wasted. CAHSR is terribly designed, terribly managed, terribly constructed, and terribly expensive. It has also probably done significant damage to the American political will for HSR.
