Re:?Increasing diesel trains cited as health risk (Aug. 20)

I read with disbelief that the Toronto medical officer of health would write a letter discouraging the enhancement of public transit of any nature (diesel or not).

While an increase in the number of diesel trains on the Georgetown GO corridor may cause a small localized increase in air pollution, the real issue is that for every train added to the route, there is the potential of removing hundreds and even thousands of cars from the road with a large net decrease in air pollution to the GTA as a whole.

One would think a medical health officer would do everything in their power to increase public transit, not put up road blocks to slow it down.

While electric trains may be healthier than diesel trains, public transit is a vast improvement over individual cars for the overall health and environment for the people of Ontario.
