====San Antonio area====
On June 28, 2004, a UP train collided with an idle [[BNSF Railway|BNSF]] train in [[Macdona, Texas|a San Antonio suburb]]. In the course of the derailment, a 90-ton [[tank car]] carrying liquified [[chlorine]] was punctured. As the chlorine vaporized, a toxic "yellow cloud" formed, killing three and causing 43 hospitalizations. The costs of cleanup and property damaged during the incident exceeded $7 million.<ref>{{Cite web |title=Chlorine Rail Car Incident |url=http://www.aristatek.com/newsletter/0708August/TechSpeak.pdf |access-date=April 18, 2010 |publisher=Aristatek}}</ref> [[File:UP Macdona Derailment.jpg|thumb|Deadly [[derailment]] in [[Macdona, Texas]], on June 28, 2004|alt=]]
Investigations of the Macdona incident revealed several serious safety lapses on the part of the Union Pacific and its employees, including employees not following the company's own safety rules.<ref name="nytimes.com">{{Cite news |last1=Nordberg |first1=Jenny |last2=Bogdanich |first2=Walt |date=November 17, 2004 |title=Regulators Plan to Step Up Union Pacific Safety Checks |url=https://www.nytimes.com/2004/11/17/politics/17rail.html |work=The New York Times}}</ref> While the immediate cause of the derailment was the UP crew's "fatigue", chlorine [[tank car]]s had been improperly placed near the front of the train, a danger in the case of derailment.<ref>{{Cite web |title=NTSB – Remarks by Robert L.

The Macdona incident was not the first derailment in the [[San Antonio]] area. Between May and November 1994, Union Pacific trains derailed five times, killing at least 4 people.<ref>{{Cite news |date=November 11, 2004 |title=Man Killed in Fifth Train Derailment in San Antonio Since May |url=https://www.nytimes.com/2004/11/11/national/11derail.html |access-date=April 18, 2010 |work=The New York Times}}</ref> Between June 2004 and March 2005, 10 trains derailed, killing as many people.<ref name="query.nytimes.com">{{Cite news |last=Bogdanich |first=Walt |date=March 19, 2005 |title=Texas Has Pact With Railroad To Move Lines |url=https://query.nytimes.com/gst/fullpage.html?res=950DE7DA113CF93AA25750C0A9639C8B63 |work=The New York Times}}</ref>

In the aftermath of Macdona, the [[Federal Railroad Administration]] signed a compliance agreement with the railroad in which the railroad promised to rectify the "notable deficiencies" that regulators found.<ref name="nytimes.com" /><ref name="query.nytimes.com" /> But the relative impunity UP seemed to exhibit regarding the derailment led to suggestions that the FRA was far "too cozy&nbsp;... to the railroads."<ref name="nytimes.com" /> In March 2005, Texas Governor [[Rick Perry]] supported a plan to reroute trains around large urban population centers in Texas, including San Antonio, but such a plan was purely voluntary and had no timetable associated.<ref name="query.nytimes.com" />
