Please see links below for both the Deadly Crossing full report (produced by Forest Ethics, Waterkeeper Alliance and Riverkeeper) and video. Here's an intro quoted from the report.
"Citizens Report on Rail Bridges to shed light on this potential threat, a grassroots network of advocates conducted 250 citizen inspections of rail bridges in 15 different states. Riverkeeper, ForestEthics, and 22 Waterkeeper organizations noted and photographed bridges showing signs of concern. This report details the results of these citizen inspections and outlines our call to action for oil train and rail bridge safety. Citizen inspectors identified deficiencies,
defined as cracks or pieces missing, significant rusting, and/or deterioration or rotting of
the foundation in 46 percent of the bridges inspected (114 of 250 bridges inspected).
While Waterkeeper inspectors may not be bridge engineers, they are advocates with legal, public policy, and scientific experience monitoring waterways for water pollution and threats to human health and the environment. They found that failing, undermined, and missing structural materials were most common where foundations sit in waterways, especially below the high water mark. Waterkeepers observed makeshift repairs, including
concrete patches and use of metal straps and brackets to reinforce failing and missing beams.
In several cases Waterkeepers were present when crude oil unit trains passed over bridges and
observed flexing, slumping, and vibrations that caused concrete to crumble and slough off.
Crumbling rail bridge infrastructure was
common and easily visible. The most
commonly identified deficiencies were:
• Missing and crumbling concrete
• Erosion of pilings
• Exposed rebar
• Loose and broken wooden/creosote beams
• Severe rusting and/or holes in structural steel
• Loose, and missing bolts
• Uneven tracks
• Crossties in poor condition
• Missing spikes
• Failing retaining walls"
