What do they spray on railroad tracks?
One of the most common types of chemicals linked to railroad workers are the herbicides used by track workers to kill weeds and vegetation. Railroad workers that come into contact with glyphosate, also a key ingredient in many weed killers, could suffer serious health issues, including cancer.
Why do they put gravel under railroad tracks?
The crushed stones are what is known as ballast. Their purpose is to hold the wooden cross ties in place, which in turn hold the rails in place. The answer is to start with the bare ground, and then build up a foundation to raise the track high enough so it won’t get flooded.
Why are there stones alongside railway tracks?
1. The stones don’t allow vegetation to grow on railway tracks which could weaken the ground on which the railway lines run. 2. Track ballast also keeps water from reaching the track on a regular basis and softening the ground.
What do power companies use to kill weeds?
Q. I noticed that this year the power company decided to poison the undergrowth instead of cutting it. I don’t know if this is killing animals and insects. There may be groundwater contamination issues.
How do railroads trim trees?
Two of the crews regularly trim trees using a mechanical tree cutter mounted on a hi-rail vehicle. The unit features a specially designed cutter head that can maneuver under, over and around the overhead catenary system.
What is Arsenal herbicide?
Arsenal® herbicide is an aqueous solution to be mixed with water and a surfactant and applied as a spray solution to control undesirable vegetation growing within specified aquatic sites, forestry sites, pasture/rangeland and nonagri- cultural lands.
How does railway ballast work?
Railway ballast is packed beneath the train rails to interlock with the capping layer subgrade and provide a uniform support layer. More ballast is also packed between the sleepers and rail itself to lock them in place to resist the high loads from passing trains (Figure 1).
Can weeds be electrocuted?
In addition to killing weeds, electrocution also affects viability of surviving weed seeds. The most impact is seen in waterhemp, where about 65\% of seeds become nonviable. Electrocution is not new to the weed management world, says Bradley.
Where does glyphosate come from?
Glyphosate is derived from an amino acid called glycine and plant cells treat glyphosate as though it were amino acid. Plants use amino acids to build things like enzymes and proteins that it needs in order to grow, through a process called amino acid synthesis.
How do railroads get rid of weeds?
To keep vegetation growth in check, railroads have programs in place that aim to proactively eradicate weeds before they grow, kill those that already have sprouted, and control tree and bush growth. And they rely on a combination of herbicide spraying and mechanical brush cutting to do it.
How does SEPTA manage vegetation on its railroad tracks?
The Southeastern Pennsylvania Transportation Authority (SEPTA) hasn’t changed its vegetation-management approach much the past few years. The passenger railroad employs several contractors to spray weeds and cut brush to keep rights of way clear from overgrowing foliage.
How often should you use herbicides on your railroad tracks?
“I suggest railroads use an herbicide for a couple of years, and then completely change the chemistry every third year to take out weeds that are starting to get resistant.” However, there aren’t many herbicides on the market for rail applications.
What is the best ground defoliant for railroad tracks?
Some railroads haved used Ureabor, a very strong and long-lasting ground defoliant, to more or less “permanently” treat areas where vegetation needed to be removed. Ureabor is a soil sterilant and can last years. It must be applied very carefully and must not get into water drainages. [ Reply To This Message ] [ Quote ]
