GO will not use Tier 4 trains on the Georgetown line when it opens in 2015, according to InsideToronto. Instead GO will use much dirtier Tier 2 engines.
GO Transit presented information about the line at two community meetings on June 23 and 24.
In the story boards, GO says they will use Tier 4 engines, which vastly reduce particulate and nitrous oxide emissions, when the new engines are “commercially available”. They anticipate that will be in 2017.
The line is due to open in 2015, however. Tier 2 trains would therefore be in use for two years if everything goes according to plan.
