Of course, you've been keeping up-to-date with service and construction issues on St. Clair, with the other TTC column, Transit Today.

The updates will still be reported there, and this column will be about the technical aspects of the streetcar track construction.

What kind of new rails are being used; what are the large, shiny, grey poles for; what type of shelters will be on the islands; this is just a sampling of the type of question that will be answered.

If you have questions about any of the construction techniques or the material used, or anything else technical, please send your query to super@mystclair.com. Hope to hear from you soon.
