World's Fastest Cyclist Hits 82.3 MPH
The fastest that I've recorded myself on my bike is 73.5 km/hr, downhill. That was last Saturday. I can only imagine going another 60 km/hr faster. Crazy.

Mr. [Fungineer]:
By way of this e-mail I am going to ask my colleague out of Montreal to respond to some of the specifics in your inquiry. She is more familiar with the treatment that was carried out in the Peterborough area and the herbicide(s) that were used.
To quickly answer some of your general questions / comments:
Yes, appropriate environmental precautions are taken during the herbicide application process. All of our weed spray trucks are equipped with shrouded booms to minimize the potential for drift and spraying in windy conditions is not permitted (see attached photos). As is clearly evident in your photos the weed treatment has been confined to a narrow band on and immediately adjacent to our tracks. Our contract applicators are all provincially certified and must adhere to provincial regulations governing industrial herbicide applications. All herbicides that we use are extensively tested before being federally approved for use by the PMRA division of Health Canada and have a low acute toxicity to mammals and aquatic organisms.
At CP we control vegetation / weeds growing in the track ballast (rock section underlying the track) for a variety of safety reasons. Most notably, excessive weed growth in the ballast section can impeded drainage which can lead to track instability issues such as mud pumping. We also have a variety of hi-tech instrumentation to inspect track geometry and other conditions that rely on a clear line of sight. Visual track inspections, by trained inspectors, are also required by Transport Canada at least once per week. Excessive weed growth can obscure track defects creating challenging conditions for the aforementioned automated and visual safety inspections. In areas where railcar inspection or switching is required, areas immediately adjacent to tracks also need to be kept weed free in order to reduce the potential for slipping and tripping hazards, particularly for nighttime operations.
