November 2001 Edition Train à grande vitesse causes distress To ride on the French train à grande vitesse is an almost unbelievable experience in ultra-high-speed travel, rivalling the virtual reality of Huxley's Brave New World. As a boy, I once sat in a bus going from Paris to Nice. While the scenery was a delight, the cramped conditions on a ten hour journey remain a painful memory to this day. Today, there is little actual sensation of speed as the TGV whisks passengers along from Paris to the Mediterranean at 300 kilometres an hour and the rock-like stability and passenger space makes it much more comfortable than cramped airline travel. And as railway stations are usually located in downtown areas, a TGV can equal and sometimes exceed the speed of jet travel when its convenient downtown location is factored into total travelling time.

Mass flowmeter chlorine gas measurement at historic water treatment plant The R.C. Harris Filtration Plant is an historic landmark on Toronto's lakefront. Constructed in the late 1930s, this architectural masterpiece has been declared a National Historic Civil Engineering Site. Inside the massive and silent marble halls, a lot of high-tech instrumentation is quietly at work ensuring safe drinking water for the citizens of Toronto. The R.C. Harris plant can provide for up to 950 megalitres per day and supplies 45% of the city's water. Some three years ago, a team was established at R.C. Harris to explore new technologies available to the industry. One of the goals they wanted to achieve was an accurate and instantaneous measurement of chlorine gas in the post-chlorination stage.
