The Toronto Transit Commission (TTC) is preparing for its annual geometric track survey designed to identify minor defects in the transit systemâs tracks. Scheduled to commence next week, this survey follows a successful effort last year that led to the implementation of numerous slow zones. Although the number of slow zones has improved from 33 to 12, TTC's Stuart Green indicates it is unrealistic to expect their complete elimination. The survey employs advanced laser technology to assess track integrity and geometry, incurring costs around $250,000 USD per session.
TTC spokesperson Stuart Green noted, "While we have no idea how many minor defects the survey might find, we assume it will find some."
